ITEM 1.   BUSINESS 

Overview

PART I 

 Trevena, Inc. is a biopharmaceutical company focused on the development and commercialization of innovative treatment options

that target and treat diseases affecting the central nervous system, or CNS. Unless the context otherwise requires, we use the terms
“Trevena,” “company,” “we,” “us,” and “our” to refer to Trevena, Inc.

Using our proprietary product platform, we have identified and are developing the following product candidates:

· Oliceridine injection: We are developing oliceridine, a G protein biased mu-opioid receptor, or MOR, ligand, for the

management of moderate-to-severe acute pain in hospitals or other controlled clinical settings where intravenous, or IV,
administration of opioids is warranted. We have completed two pivotal Phase 3 efficacy studies (APOLLO 1 and APOLLO
2) of oliceridine in moderate-to-severe acute pain following bunionectomy and abdominoplasty, respectively. In both studies,
all dose regimens achieved their primary endpoint of statistically greater analgesic efficacy than placebo, as measured by
responder rate. We also have completed a Phase 3 open-label safety study (ATHENA) in which 768 patients were
administered oliceridine to manage pain associated with a wide range of procedures and diagnoses. In late 2017, we
submitted the oliceridine new drug application, or NDA, to the United States Food and Drug Administration, or FDA. On
November 2, 2018, the FDA issued a complete response letter, or CRL, with respect to our NDA for oliceridine. In the CRL,
the FDA requested additional clinical data on the QT interval and indicated that the submitted safety database was not of
adequate size for the proposed labeling. The FDA also requested certain additional nonclinical data and validation reports. On
January 28, 2019, we announced the receipt of the official Type A meeting minutes from the FDA regarding the CRL
wherein the FDA agreed that our current safety database will support labeling at a maximum daily dose of 27 mg. The FDA
also agreed that we can conduct a study in healthy volunteers to collect the requested QT interval data and that the study
should include placebo- and positive-control arms. We have submitted a detailed protocol and analysis plan to the FDA and,
following receipt of FDA feedback, anticipate initiating the study in the first half of 2019. To address remaining items in the
CRL, the FDA indicated that we should include supporting nonclinical data related to the characterization of the 9662
metabolite and the remaining product validation reports when we resubmit the oliceridine NDA.

·

·

TRV250: We are developing TRV250, a G protein biased delta-opioid receptor, or DOR, as a compound with a potential
first-in-class, novel mechanism for the treatment of acute migraine. TRV250 also may have utility in a range of other CNS
indications. Because TRV250 selectively targets the DOR, we believe it will not have the addiction liability of conventional
opioids or have other mu-opioid related adverse effects like those seen with morphine or oxycodone. In June 2018, we
announced the successful completion of our first-in-human Phase 1 study of TRV250. Data from this healthy volunteer study
showed safety, tolerability, and pharmacokinetics supporting the advancement of TRV250 to Phase 2 proof of concept
evaluation in patients.

TRV734: We also have identified and have completed the initial Phase 1 studies for TRV734, a new chemical entity, or
NCE, targeting the same novel mechanism of action at the MOR as oliceridine. TRV734 was designed to be orally available,
and its mechanism of action suggests it may offer valuable benefits for two distinct areas of important unmet medical need:
acute and chronic pain, and maintenance therapy for patients with opioid use disorder. We are collaborating with the National
Institute on Drug Abuse, or NIDA, to further evaluate TRV734 for the management of opioid use disorder. We intend to
continue to focus our efforts for TRV734 on securing a development and commercialization partner for this asset.

We also are evaluating a set of novel S1P modulators that may offer a new, non-opioid approach to managing chronic pain. In the

fourth quarter of 2018, we identified a new product candidate, TRV045, a novel S1P modulator that

4

 
Table of Contents

we believe may offer a new, non-opioid approach to managing chronic pain. We anticipate beginning investigational new drug, or IND,
enabling work in 2019, and we will continue to evaluate the progression of this asset to an IND, either by ourselves or with a partner.

Our Pipeline

Oliceridine Injection

Oliceridine is a G protein biased MOR ligand in development for the management of moderate-to-severe acute pain in hospitals or

other controlled clinical settings where IV opioid therapy is warranted. It is an NCE with a novel mechanism of action at the MOR that
enables more selective targeting of newly discovered pathways with the potential for fewer side effects.

Disease and treatment options

The typical treatment paradigm in the United States for the management of moderate‑to‑severe acute pain is to initiate injectable

(IV) pain medication in the preoperative or immediate postoperative period to provide rapid and effective pain relief. Conventional IV
opioid analgesics, such as morphine, fentanyl, and hydromorphone, have been core components of pain management protocols in the
immediate postoperative period. The clinical effectiveness of conventional opioid agonists is limited by severe dose dependent side effects
such as respiratory depression, nausea, vomiting, and constipation, which can be exacerbated by accumulation of active metabolites and by
reduced renal clearance in patients with impaired kidney function. Currently available IV opioid options offer either fast onset with short
duration of action (e.g. IV fentanyl), or slower onset with longer duration (e.g. IV morphine). These pharmacokinetic and
pharmacodynamic, or PK/PD, profiles create some practical challenges for healthcare providers in certain clinical practice situations.

Injectable non‑opioid analgesics are often used together with IV opioids in so-called multimodal protocols for post‑surgical pain
management; however, these drugs, such as IV non‑steroidal anti‑inflammatory drugs, or NSAIDs, IV acetaminophen, or local anesthetics
such as bupivacaine, have their own potential for cardiovascular, hepatic and gastrointestinal side effects. In addition, none of these
non‑opioid analgesic approaches offers great enough efficacy to manage severe acute pain as a monotherapy in many patients. We believe
that there remains significant unmet need for a highly effective IV opioid analgesic agent with an improved safety, tolerability, and/or
PK/PD profile.

Clinical development

We are developing oliceridine for the management of moderate‑to‑severe acute pain in hospitals or other controlled clinical

settings where IV administration is warranted. In the future, we also may explore other formulations, such as transmucosal administration
for breakthrough pain in additional, separate clinical trials.

Below is a summary of the clinical development work undertaken for oliceridine.

ATHENA Phase 3 Open Label Safety Study

We conducted a Phase 3, open label, multicenter study evaluating the safety and tolerability of oliceridine in patients with

moderate-to-severe pain caused by surgery or medical conditions. The trial was designed to model real-world use, including the use of
multi-modal analgesia. Patients were treated with oliceridine on an as-needed basis via IV bolus, patient-controlled analgesia, or PCA, or
both, as determined by the investigator. The primary objective was to assess the safety and tolerability of oliceridine. Pain intensity was
measured as a secondary endpoint.

In the ATHENA study, 768 patients were treated with oliceridine. The most common procedures were orthopedic, gynecologic,

colorectal, and general surgeries. Patients at elevated risk of opioid-related adverse events were well represented; more than 30% of patients
were 65 years or older, and approximately 50% of patients were obese, with body mass index (BMI) >30 kg/m2. Only 2% of patients
discontinued for adverse events, and 4% of patients discontinued for lack of efficacy. The most common adverse events were nausea,
constipation, and vomiting, with prevalence lower than in the APOLLO studies. Adverse event rates associated with oliceridine
administered by PCA and as-needed bolus dosing were similar, supporting the potential use of oliceridine in both administration paradigms.

APOLLO 1 and APOLLO 2 Phase 3 Studies

We have conducted two pivotal efficacy trials evaluating oliceridine in patients with moderate-to-severe acute pain: the APOLLO

1 study, which evaluated pain for 48 hours following bunionectomy, and the APOLLO 2 study, which evaluated pain for 24 hours following
abdominoplasty. In February 2017, we announced positive top line results from the APOLLO 1 and APOLLO 2 studies. In both studies, all
dose regimens achieved the primary endpoint of statistically greater analgesic efficacy than placebo, as measured by responder rate.

The APOLLO 1 and APOLLO 2 studies were both Phase 3, multicenter, randomized, double-blind, placebo- and active-controlled

studies of oliceridine. During the study period, a loading dose of placebo, morphine (4 mg), or oliceridine (1.5 mg) was administered first,
and then patients used a PCA button to dose themselves as often as every 6 minutes with the same study drug: 1 mg morphine, or 0.1 mg,
0.35 mg, or 0.5 mg oliceridine. If PCA dosing was inadequate to control pain, patients could request supplemental study medication (2 mg
morphine or 0.75 mg oliceridine, no more than once an hour). If the study medication regimen did not adequately manage pain, patients
could opt for an NSAID rescue analgesic. Placebo loading, demand, and supplemental doses were volume-matched.

All endpoints were the same in both studies, except that dosing and pain assessment were for 48 hours in APOLLO 1 and 24 hours

in APOLLO 2. Efficacy was measured by a responder analysis, which defined a responder as a patient who experienced at least a 30%
reduction in their sum of pain intensity difference at the end of the treatment period without either early discontinuation (for lack of efficacy
or safety/tolerability) or use of rescue medication. Non-inferior efficacy compared to morphine and superior efficacy compared to morphine
were key secondary endpoints. Respiratory safety events were defined as clinically relevant worsening of respiratory status, including
oxygen saturation, respiratory rate, or sedation. The product of the frequency and conditional duration of these events was reported as
respiratory safety burden, a key secondary endpoint. Additional measures of respiratory safety included prevalence of oxygen saturation
less than 90% and prevalence of supplemental oxygen use. Measures of gastrointestinal tolerability included use of rescue antiemetics,
vomiting, and spontaneously reported nausea.

APOLLO 1 (bunionectomy)

·

·

All three oliceridine regimens (0.1 mg, 0.35 mg, and 0.5 mg on-demand doses) achieved the primary endpoint with
statistically superior responder rates compared to placebo at 48 hours (p<0.0001, adjusted for multiplicity).

The 0.35 mg and 0.5 mg oliceridine dose regimens demonstrated efficacy comparable to morphine at 48 hours based on
responder rate (both doses p<0.005 for non-inferiority to morphine). Both doses were also comparable to morphine for rates
of rescue analgesic use.

·

Following the 1.5 mg initial loading dose, all oliceridine regimens demonstrated rapid onset with statistically significant
efficacy within 5 minutes (p<0.05).

Oliceridine exhibited a dose-related trend of improved respiratory safety burden in all three oliceridine dose regimens
(p<0.05 for the 0.1 mg regimen vs. morphine). Consistent with this, in all dose regimens oliceridine showed dose-related
trends of reduced respiratory safety events (P<0.05 for 0.1 mg and 0.35 mg regimens vs. morphine through the first 12 hours
of dosing), prevalence of oxygen desaturation (O2<90%) and lower prevalence of supplemental oxygen use (p<0.05 for the
0.1 mg regimen vs. morphine for both measures).

Oliceridine exhibited less antiemetic use compared to morphine (p<0.05 for all oliceridine regimens vs. morphine).
Consistent with this, oliceridine showed dose related trends of lower prevalence of nausea and vomiting in all three
oliceridine regimens (p<0.05 for the 0.1 mg regimen vs. morphine).

APOLLO 2 (abdominoplasty)

·

·

·

·

·

All three oliceridine dose regimens achieved the primary endpoint with statistically superior responder rates compared to
placebo at 24 hours (adjusted p<0.05 for the 0.1 mg regimen; adjusted p<0.001 for the 0.35 mg and 0.5 mg regimens).

The 0.35 mg and 0.5 mg oliceridine dose regimens demonstrated efficacy comparable to morphine at 24 hours based on
responder rate (p<0.05 for non-inferiority of the 0.35 mg regimen vs. morphine). Both doses were also comparable to
morphine for rates of rescue analgesic use.

Following the 1.5 mg initial loading dose, all oliceridine regimens demonstrated rapid onset with statistically significant
efficacy within 5 to 15 minutes (p<0.05).

Oliceridine showed a dose-related trend of improved respiratory safety burden in all three oliceridine dose regimens (p<0.05
for the 0.1 mg regimen vs. morphine). Consistent with this, for all dose regimens oliceridine showed dose-related trends of
reduced respiratory safety events, prevalence of oxygen desaturation (O2<90%) and lower prevalence of supplemental
oxygen use (p<0.05 for the 0.1 mg regimen vs. morphine for all measures).

Oliceridine showed a dose-related trend of less antiemetic use than morphine for all three oliceridine regimens (p<0.05 for
the 0.1 mg oliceridine regimen vs. morphine). Consistent with this, oliceridine showed dose-related trends of lower
prevalence of nausea and vomiting (p<0.05 for the 0.1 mg regimen vs. morphine for both nausea and vomiting; p<0.05 for
the 0.35 mg regimen vs. morphine for vomiting).

In both studies, oliceridine was generally well-tolerated. The most common drug-related adverse events were nausea, vomiting,

headache, and dizziness.

Phase 2b trial of oliceridine in acute postoperative pain following abdominoplasty

The aim of our Phase 2b clinical trial was to evaluate the efficacy, safety and tolerability of oliceridine in the management of

postoperative pain using morphine as a benchmark, utilizing on demand dosing to reflect standard clinical practice. This Phase 2b trial was a
randomized, double blind, placebo and active controlled trial of oliceridine in which we enrolled 200 patients with moderate-to-severe acute
postoperative pain after abdominoplasty surgery. Two regimens of oliceridine were tested: the first consisted of a 1.5 mg intravenous
loading dose with 0.1 mg self-administered on demand doses as often as every six minutes using a PCA device; the second consisted of a
1.5 mg loading dose with 0.35 mg on demand doses as often as every six minutes using a PCA device. A commonly used morphine PCA
regimen also was tested, consisting of a 4 mg loading dose with 1 mg on demand doses as often as every six minutes. Placebo was
administered as a loading dose and on demand doses were volume matched to the active regimens. Rescue medication consisting of
ibuprofen or oxycodone was used in all groups.

Table of Contents

In August 2015, we reported top line results from this trial. Oliceridine demonstrated statistically significant pain reduction
compared to placebo and comparable efficacy to morphine. Oliceridine provided rapid reduction in average pain scores, consistent with the
previous Phase 2 trial where oliceridine showed more rapid onset of meaningful pain relief than morphine. Rescue analgesic use was
similar for both oliceridine and morphine, and less than half the rate of rescue analgesic use for placebo. In this study, the oliceridine groups
had a significantly lower prevalence (percentage of patients) of hypoventilation events (a measure of respiratory safety), nausea, and
vomiting than the morphine group. The most frequently reported adverse events, associated with oliceridine were nausea, vomiting,
hypoventilation and headache. Opioid related adverse events were generally less frequent in the oliceridine groups compared to morphine.
No drug related serious adverse events were reported in the study.

Phase 2a/b trial of oliceridine in acute postoperative pain following bunionectomy

The aim of our Phase 2a/b clinical trial was to evaluate the efficacy and tolerability of oliceridine in the management of
postoperative pain using morphine as a benchmark, using fixed dose and dose interval to characterize the performance of oliceridine. The
trial was a multicenter, randomized, double blind, placebo and active controlled, multiple dose, adaptive trial in 333 women and men
undergoing a primary unilateral first metatarsal bunionectomy surgery at four sites in the United States. Patients were randomized after
surgery to receive oliceridine, morphine or placebo to manage their pain. Pain intensity was measured using validated numeric rating scales
ranging from ten (most severe pain) to zero (no pain) at multiple time points up to 48 hours. Based on these scales, analgesic efficacy was
assessed with a time weighted average change in pain score over 48 hours—a well-established measure of changes in the intensity of pain
over time and an FDA recommended endpoint for pain studies.

In November 2014, we announced top line data from this trial. At doses of 2 mg and 3 mg of oliceridine administered every three

hours, the trial achieved its primary endpoint of statistically greater pain reduction than placebo for 48 hours, which we believe
demonstrated proof of concept for oliceridine. Over the 48-hour trial period, the 3 mg dose of oliceridine administered every three hours
also showed statistically superior analgesic efficacy compared to the 4 mg dose of morphine administered every four hours. Additionally, in
the first three hours of dosing, when pain was most severe, the 1 mg, 2 mg, and 3 mg doses of oliceridine demonstrated superior analgesic
efficacy in the trial compared to placebo, and the 2 mg, and 3 mg doses of oliceridine demonstrated superior analgesic efficacy compared to
the 4 mg dose of morphine.

There were no serious adverse events reported in the trial. Both the 2 mg and 3 mg doses of oliceridine showed overall tolerability

over the 48-hour trial period similar to that of the 4 mg dose of morphine administered every four hours. The most frequently reported
adverse events associated with oliceridine were dizziness, headache, somnolence, nausea, vomiting, flushing and itching. Adverse effects
were generally dose related.

Phase 1 clinical studies of oliceridine

We also have completed a number of Phase 1 clinical studies of oliceridine. These included two single ascending dose studies of

oliceridine given as a 60-minute continuous infusion or a 2-minute bolus infusion that showed dose related increases in plasma exposure
and pupil constriction, a biomarker for CNS opioid activity across a range of doses that were generally well tolerated.

In 2013, we completed a Phase 1b proof of concept exploratory trial in healthy male subjects. The aims of this trial were to
characterize the analgesic efficacy and safety and tolerability of a single dose of oliceridine as compared to a single 10 mg dose of morphine.
We used a well-established evoked pain model, the cold pain test, to evaluate the analgesic effects of oliceridine by measuring the time to
hand removal, or latency, from a temperature controlled cold water bath. At both the 3.0 mg and 4.5 mg doses, oliceridine showed superior
efficacy as compared to a 10 mg morphine dose that was statistically significant with a p value of less than 0.05 at the ten- and thirty-minute
time points after dosing. The durability of the analgesic effect was similar to morphine. In addition, the time to peak effect was more rapid
than that for morphine. Overall, oliceridine was well tolerated in the trial. Subjects receiving oliceridine showed less severe nausea and less
frequent vomiting at the 1.5 mg and 3.0 mg doses as compared to a 10 mg dose of morphine. Oliceridine also showed less respiratory
depression compared to morphine over 4 hours.

8

 
Table of Contents

In October 2014 we completed an adaptive, multiple ascending dose study of oliceridine in more than 50 healthy subjects. The
safety, tolerability, pharmacokinetic and pharmacodynamics results of this study were consistent with the early Phase 1 studies described
above. Recently, we also successfully completed an absorption, distribution, metabolism, and excretion study, with results consistent with
the lack of known active oliceridine metabolites. We also completed a thorough QT study, a renal impairment study which showed no
evidence of altered PK/accumulation in patients with renal failure compared to healthy patients, and a human abuse liability study which
showed that oliceridine had similar abuse liability as IV morphine when administered at a comparably analgesic dose. In addition, we have
completed a study in patients with underlying hepatic impairment, which showed that less frequent oliceridine dosing may be required in
patients with severe hepatic impairment.

Regulatory

In late 2017, we submitted the NDA for oliceridine to the FDA and on November 2, 2018, the FDA issued a CRL related to the

NDA. In the CRL, the FDA requested additional clinical data on the QT interval and indicated that the submitted safety database was not of
adequate size for the proposed labeling at a maximum daily dose of 40 mg. The FDA also requested certain additional nonclinical data and
validation reports. On January 28, 2019, we announced the receipt of the official Type A meeting minutes from the FDA regarding the CRL
wherein the FDA agreed that the submitted safety database will support labeling at a maximum daily dose of 27 mg. The FDA also agreed
that we can conduct a study in healthy volunteers to collect the requested QT interval data and that the study should include placebo- and
positive-control arms. We have submitted a detailed protocol and statistical analysis plan to the FDA for the healthy volunteer study and,
following receipt of FDA feedback, anticipate initiating the study in the first half of 2019. To address remaining items in the CRL, the FDA
indicated that we should include supporting nonclinical data related to the characterization of the 9662 metabolite and the remaining product
validation reports when we resubmit the oliceridine NDA.

In December 2015, the FDA granted Fast Track designation to oliceridine for the management of moderate to severe acute pain.

The Fast Track program is designed to facilitate the development and review of drugs intended to treat serious conditions with unmet
medical needs by providing sponsors with the opportunity for frequent interactions with the FDA.

In February 2016, based on the preliminary evidence from our Phase 2 clinical studies of oliceridine, the FDA granted
Breakthrough Therapy designation to oliceridine for the management of moderate to severe acute pain. Breakthrough Therapy designation
is granted by the FDA to new therapies intended to treat serious or life-threatening conditions and for which preliminary clinical evidence
indicates that the drug may demonstrate substantial clinical improvement over available therapies. If granted, the FDA regularly reviews the
Breakthrough Therapy designation for a product candidate to ensure that any additional clinical evidence continues to support this
designation. In March 2019, based on its review of data from the Company’s Phase 3 studies of oliceridine, the FDA informed Trevena that
under the conditions studied, these data were not sufficient to support the continuation of the FDA’s previously granted Breakthrough
Therapy designation. The Company does not expect the absence of Breakthrough Therapy designation to impact the timing of the FDA’s
review of the oliceridine new drug application following resubmission.  

Commercialization

According to 2017 IQVIA hospital charge detail data, approximately 45 million patients in the United States were treated with an

IV opioid in the hospital setting. The majority of doses of IV opioids administered were in the inpatient setting where approximately 15
million patients were treated with multiple doses for an average of one to two days. Patients treated in the hospital outpatient or ambulatory
surgical centers may also receive one or two doses of IV opioids for postsurgical or medical pain. The Centers for Disease Control and
Prevention, or CDC, has estimated that approximately 100 million surgical and invasive diagnostic procedures occur annually in the United
States. Accordingly, if approved, we believe that there is a large potential commercial opportunity for oliceridine in the management of both
surgical and medical acute pain in hospital and ambulatory surgical centers.

Table of Contents

If oliceridine ultimately receives regulatory approval, we plan to commercialize it in the United States, either on our own or with a

commercial partner. Outside the United States, we expect to continue to seek collaborators to commercialize oliceridine to offset risk and
preserve capital.

To commercialize oliceridine in the United States, we intend to utilize a hospital-focused specialty sales force targeting surgeons,

anesthesiologists, hospitalists, and other healthcare providers with acute post-surgical or medical pain management responsibility. While we
believe that the greatest opportunity for oliceridine will ultimately be in the hospital inpatient setting where acute pain is typically more
severe, the onset and duration of analgesia seen with oliceridine may be well suited to hospital outpatient and ambulatory surgical centers.
Hospital trend data also indicates that ambulatory surgical procedures now outnumber and are growing faster than inpatient surgeries in the
United States. Because many surgeons and anesthesiologists manage both inpatient and outpatient cases, we believe that early physician
experiences with oliceridine in ambulatory surgery may support subsequent use in the inpatient setting.

We estimate that approximately 50% of the 15 million IV opioid treated hospital inpatients may be at increased risk of opioid-
related adverse events such as respiratory depression or post-operative nausea and vomiting. We believe that many of these patients are
elderly and have comorbid conditions, driving inpatient surgical complexity and length of stay. Population and hospital trend data indicates
that these patient groups will continue to grow and be an area of focus for inpatient care. Managing these patients and adverse events results
in a significant cost burden to the hospital system. Given these changing dynamics in the hospital marketplace and the increased emphasis
on clinical and economic outcomes, we expect our commercialization plans to include health economic information framing the budget
impact of oliceridine through a potential reduction in the adverse events seen with conventional IV opioids in these patients.

According to 2017 data from Symphony Health Solutions, approximately 1,200 U.S. hospitals are responsible for 70% of the

annual volume of conventional IV opioid drugs prescribed. We expect to identify a subset of these hospitals that utilize high volumes of IV
opioids in pain management and have rapidly adopted new branded analgesic agents in the past as the initial account targets for oliceridine
at launch. We will work to secure Pharmacy and Therapeutics Committee approval and subsequent utilization of oliceridine at these
hospitals.

Manufacturing

We have completed process development of the active pharmaceutical ingredient, or API, and have manufactured multiple

commercial scale batches using our proposed commercial process under current good manufacturing practices, or cGMP, conditions. We
also have completed drug product process development and have manufactured multiple batches of drug product using the proposed
commercial process under cGMP conditions.

For oliceridine, we have established commercial supply agreements for the manufacture of the API and finished (compounded,

filled and packaged) drug product. Alcami Corporation, or Alcami, is contracted to supply 100% of our commercial API from its
Germantown, WI manufacturing facility. We have existing commercial supply agreements with two separate companies for the supply of
drug product. Alcami is contracted to supply commercial drug product from its facilities in Charleston, SC and Wilmington, NC and was
included as part of our NDA submission. Pfizer CentreOne (formerly Hospira) is also contracted to supply commercial drug product from
its facility in McPherson, KS, but was not included in our NDA submission. If approved, we anticipate that oliceridine will be classified as a
Schedule II controlled substance. All third-party facilities throughout the supply chain have the appropriate licenses from the U.S. Drug
Enforcement Administration, or DEA, for handling Schedule II controlled substances according to each of their respective contractual roles
(manufacturing, testing, distribution, etc.).

Competition

If oliceridine is approved for IV management of moderate-to-severe acute pain, it will compete with generic IV opioid analgesics,
such as morphine, hydromorphone and fentanyl. The analgesic effectiveness of these agents is limited by well-known adverse side effects,
such as respiratory depression, nausea, vomiting, constipation, and post-operative ileus, which can be exacerbated by the way these
molecules are metabolized or cleared. Oliceridine also may compete against, or be used in combination with, OFIRMEV® (IV
acetaminophen), marketed by Mallinckrodt plc, EXPAREL® (liposomal bupivacaine), marketed by Pacira Pharmaceuticals, Inc.,
CALDOLOR® (IV ibuprofen), marketed by

10

 
Table of Contents

Cumberland Pharmaceuticals, and DSUVIA™ (sublingual sufentanil) marketed by AcelRx. Together with generic versions of IV NSAIDs
such as ketorolac, and generic versions of local anesthetics such as bupivacaine, these non-opioid analgesics are currently used in
combination with opioids in the multimodal management of moderate-to-severe acute pain.

We also are aware of a number of products in mid- and late-stage clinical development that are aimed at improving the treatment of

moderate-to-severe acute pain and may compete with oliceridine. AcelRx Pharmaceuticals, Inc. is developing ZALVISO™, a non-invasive
PCA device containing sublingual sufentanil. Innocoll Holdings plc. and Heron Therapeutics Inc. have proprietary long acting
reformulations of bupivacaine in development. Recro Pharma, Inc. is developing an IV version of the NSAID meloxicam. Cara
Therapeutics Inc. is developing IV and oral dose forms of a peripherally restricted Κ opioid receptor agonist, which has been administered
in combination with mu opioids in clinical trials. Avenue Therapeutics, Inc. is developing an IV version of generic opioid tramadol for
moderate-to-severe acute pain.

Intellectual property

Our oliceridine patent portfolio is wholly owned by us. The portfolio includes four issued U.S. patents (U.S. Patent Nos.
8,835,488, 9,309,234, 9,642,842, and 9,849,119), which claim, among other things, oliceridine, compositions comprising oliceridine, and
methods of using oliceridine. The issued patents are expected to expire no earlier than 2032, subject to any disclaimers or extensions, and
any U.S. patent to issue in the future is also expected to expire no earlier than 2032, subject to any disclaimers or extensions. We also have
issued patents in Australia, China, Eurasia, Europe, Hong Kong, Israel, Japan, and New Zealand, which claim among other things,
oliceridine, compositions comprising oliceridine and methods of making or using oliceridine. The foreign portfolio also includes an
application that has been allowed by the European Patent Office, which claim among other things, oliceridine, compositions comprising
oliceridine and methods of using oliceridine. We have patent applications pending in the United States, Europe, Japan, Israel, South Korea,
Brazil, Canada, and India. The issued patents and patents that could issue in the future from these allowed or pending applications outside
the United States are expected to expire no earlier than 2032, subject to any disclaimers or extensions.

TRV250

TRV250 is a G protein biased ligand targeting the delta receptor, with potential to be a first-in-class, novel mechanism for the

treatment of acute migraine. We have completed a first-in-human Phase 1 trial of TRV250, which showed safety, tolerability, and
pharmacokinetics supporting the advancement of TRV250 to Phase 2 proof of concept evaluation in patients.

Clinical development

We believe our preclinical data support targeting the delta receptor for the treatment of CNS disorders. Prior approaches to
modulate this receptor have been limited by a significant risk of seizure associated with this target. Preclinical studies in beta-arrestin
knockout mice suggest that beta-arrestin plays a role in seizures. TRV250 is a potent delta receptor ligand that selectively activates G
protein coupling without engaging beta arrestin, leading to strong efficacy in animal models of migraine and other CNS disorders with
reduced seizure liability. In the future, we may decide to seek a collaborator for TRV250 with CNS development and commercialization
expertise outside the United States.

The Phase 1 study was a two part, randomized, single-blind, placebo-controlled, single ascending dose study to evaluate the safety,

tolerability, and pharmacokinetics of subcutaneous and oral TRV250 in healthy adults. Part A assessed single subcutaneous doses in 38
subjects. Four cohorts of nine or ten subjects were randomized to receive a single dose of up to 30mg TRV250 or placebo. Part B consisted
of a single cohort of nine subjects administered either TRV250 as a single 6 mg oral dose (either as a capsule in the fed state or a capsule in
the fasted state, n=7) or placebo (as a capsule in the fed or fasted state, n=2).

Key findings of the study included:

11

 
Table of Contents

·

·

·

·

Dose-related increases in plasma concentrations following subcutaneous administration of doses up to 30 mg, with rapid
absorption in the first hour and duration of exposure appropriate for treating acute migraine;

Subcutaneous doses at and above 9 mg achieved plasma concentrations that were active in preclinical models of migraine;

Oral bioavailability similar to existing migraine medications, supporting continued development of TRV250 in oral and/or
subcutaneous formulations;

No observed drug-associated electroencephalography changes, consistent with preclinical studies in which TRV250 avoided
the seizure liability associated with previous CNS-active delta receptor agonists; and

No clinically significant changes in vital signs, laboratory values, or ECG parameters, and no severe or serious adverse events
reported.

Based on the profile of TRV250, we believe it has the potential to be a first‑in‑class treatment option for treatment of migraine.

According to Decision Resources, a healthcare consulting company, the acute migraine treatment market encompassed approximately
12 million drug‑treated patients in 2017 in the United States, representing approximately $1.5 billion of sales. We estimate that
approximately 20% to 30% of these patients either do not respond to, or cannot tolerate, the market‑leading triptan drug class, and an
additional 30% would benefit from improved efficacy compared to these drugs.

Competition

Triptans, a generic family of 5HT1B agonists, are the current standard treatment for acute treatment of migraine in the United
States, and account for 70% of sales for this indication. Other less commonly prescribed acute treatments include ergot alkaloids, and
analgesics such as opioids and NSAIDs. Various branded reformulations of triptan molecules have been launched, and we are aware of
others in development. In May 2016, Avanir Pharmaceuticals, Inc. launched a dry powder nasal delivery formulation of sumatriptan, called
ONZETRA™ Xsail™. RedHill Biopharma, Ltd. and IntelGenx Corp. resubmitted the 505(b)(2) NDA for RIZAPORT®, an oral thin film
rizatriptan formulation, to the FDA in November 2018. Eli Lilly acquired Lasmiditan, a selective 5HT1F agonist, from Colucid
Pharmaceuticals, Inc., and filed an NDA for drug in November 2018. Allergan (atogepant and ubrogepant) and Biohaven (rimegepant) both
have small molecule oral anti-calcitonin gene-related peptide, or CGRP, antagonists in Phase 3 testing for the acute treatment of migraine.

Patients suffering from frequent or chronic migraine headaches may also use preventative agents to decrease the frequency and
severity of migraines. Botox® is the historical gold standard migraine prophylactic, but certain anticonvulsants, such as topiramate, and
beta-blockers, such as propranolol, have also been used. However, a new class of anti-CGRP antibody products are being marketed for
preventative treatment of migraine: In 2018, Amgen and Novartis launched Aimovig (erenumab), Eli Lilly and Company launched Emgality
(galcanezumab), and Teva Pharmaceutical Industries Limited launched Ajovy (fremanezumab); Alder BioPharmaceuticals Inc. is
completing Phase 3 trials with its anti-CGRP antibody eptinezumab. Allergan also has migraine prevention trials underway for atogepant,
an oral small molecule GGRP antagonist.

Intellectual property

Our TRV250 patent portfolio is wholly owned by us and includes one non-provisional patent application in the United States
directed to compounds that modulate the delta receptor, which has been allowed, claiming, among other things, TRV250, compositions
comprising TRV250, and methods of using TRV250. A patent that issues from this application is expected to expire no earlier than 2036,
subject to any disclaimers or extensions. We also have patent applications pending in Australia, Brazil, Canada, China, Europe, Israel, India,
Japan, South Korea, and New Zealand. Any patents that may issue from these applications are expected to expire no earlier than 2036,
subject to any disclaimers or extensions.

TRV734

TRV734 is a small molecule G protein biased ligand of the MOR that we discovered and have developed through Phase 1 as a
first‑line, orally administered compound for the treatment of moderate-to-severe acute and chronic pain. Like oliceridine, TRV734 takes
advantage of a well‑established mechanism of pain relief by targeting the MOR, but does so with enhanced selectivity for the G protein
signaling pathway, which in preclinical studies was linked to analgesia, as opposed to the beta‑arrestin signaling pathway, which in
preclinical studies was associated with side effects. Subject to successful preclinical and clinical development and regulatory approval, we
believe TRV734 may have an improved efficacy and side effect profile as compared to current commonly prescribed oral analgesics, such
as oxycodone. In addition, TRV734 may offer valuable benefits for another unmet medical need: the management of opioid dependence
associated with opioid use disorder. In 2018, we announced that we are collaborating with NIDA to further evaluate TRV734 for this
potential indication. We intend to continue to focus our efforts for TRV734 on securing a worldwide development and commercialization
partner for this asset.

Preclinical studies

TRV734 has shown a similar profile to oliceridine in in vitro and in vivo studies. It is highly selective for the MOR where, like the

most powerful opioid analgesics, it is a strong agonist of G protein coupling. TRV734 is distinct from those analgesics in its very weak
recruitment of beta‑arrestins to the MOR. In our preclinical studies, TRV734 showed analgesic effects in preclinical pain models similar to
oxycodone and morphine. In the same studies, TRV734 caused less constipation compared to equivalently analgesic doses of oxycodone
and morphine. TRV734 is active after oral administration in mice and rats, has high oral bioavailability and has been well tolerated in
non‑human primates. We have completed three Phase 1 trials of TRV734 in healthy volunteers, including a single ascending dose study, a
multiple ascending dose study, and a pharmacokinetic study. In these studies, a total of 127 healthy volunteers were exposed to TRV734 at
doses between 2 mg and 250 mg. We incorporated measures to assess the potential for analgesic efficacy and tolerability advantages in
these studies. Based on these data and data for oliceridine, we believe that TRV734 may offer an improved efficacy profile as compared to
current opioid therapies or equivalent efficacy with an improved gastrointestinal tolerability and respiratory safety profile.

Intellectual property

Our TRV734 patent portfolio is wholly owned by us and includes one issued U.S. patent (U.S. Patent No, 9,044,469) claiming

TRV734, other compounds and/or methods of making or using the same. This patent is expected to expire no earlier than 2032, subject to
any disclaimers or extensions. We also have issued patents in Australia, China, Europe, Eurasia, Hong Kong, Israel, Japan, and New
Zealand claiming TRV734, other compounds and/or methods of making or using the same. We also have patent applications pending in the
United States, Europe, South Korea, Brazil, Canada, Israel, India, and Hong Kong. The issued patents and patents that could issue in the
future from these allowed or pending applications outside the United States are expected to expire no earlier than 2032, subject to any
disclaimers or extensions.

S1P Modulators (TRV045)

In July 2017, we disclosed a new preclinical lead optimization program targeting S1P receptors. Our compounds are all new
chemical entities, are expected to be non-addictive, and use a new mechanism of action that in preclinical models avoids the immune
suppression associated with approved and investigational S1P receptor targeted drugs. These molecules have demonstrated activity in
preclinical models of chemotherapy-induced peripheral neuropathy, neuropathic pain, and inflammatory pain. In the fourth quarter of 2018,
we identified a new product candidate, TRV045, a novel S1P modulator that we believe may offer a new, non-opioid approach to managing
chronic pain. We anticipate beginning IND-enabling work in 2019, and we will continue to evaluate the progression of this asset to an IND,
either by ourselves or with a partner.

Our S1P patent portfolio is wholly owned by us and includes one PCT application directed to compounds that that modulate the

S1P receptor. National phase applications based on this PCT application, if filed, would be filed in December 2019 and January 2020.
Patents that could issue in the future from the national phase applications would be

13

 
Table of Contents

expected to expire no earlier than 2038, subject to any disclaimers or extensions. We are aware of a certain U.S. patent owned by a third
party with claims that are broadly directed to a method of treating chemotherapy induced neuropathic pain with an S1P receptor agonist or
an S1P receptor antagonist. Although we do not believe that this is a valid patent, this patent could be construed to cover our S1P
compounds.

Intellectual Property

We strive to protect the proprietary technologies that we believe are important to our business, including seeking and maintaining
patent protection intended to cover the composition of matter of our product candidates, their methods of use, related technology and other
inventions that are important to our business. We also rely on trade secrets and careful monitoring of our proprietary information to protect
aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection.

Our success will depend significantly on our ability to obtain and maintain patent and other proprietary protection for

commercially important technology, inventions and know how related to our business, defend and enforce our patents, maintain our licenses
to use intellectual property owned by third parties, preserve the confidentiality of our trade secrets and operate without infringing valid and
enforceable patents and other proprietary rights of third parties. We also rely on know-how, and continuing technological innovation to
develop, strengthen and maintain our proprietary position in the field of modulating GCPRs with biased ligands.

One or more third parties may hold intellectual property, including patent rights, that is important or necessary to the development

of our products. It may be necessary for us to use the patented or proprietary technology of third parties to commercialize our products, in
which case we would be required to obtain a license from these third parties on commercially reasonable terms, or our business could be
harmed, possibly materially. If we were not able to obtain a license, or were not able to obtain a license on commercially reasonable terms,
our business could be harmed, possibly materially.

We plan to continue to expand our intellectual property estate by filing patent applications directed to dosage forms, methods of
treatment for our product candidates. We anticipate seeking patent protection in the United States and internationally for compositions of
matter covering the compounds, the chemistries and processes for manufacturing these compounds and the use of these compounds in a
variety of therapies.

The patent positions of biopharmaceutical companies like us are generally uncertain and involve complex legal, scientific and

factual questions. In addition, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and the
patent’s scope can be modified after issuance. Consequently, we do not know whether any of our product candidates will be protectable or
remain protected by enforceable patents. We cannot predict whether the patent applications we are currently pursuing will issue as patents in
any particular jurisdiction or whether the claims of any issued patents will provide sufficient proprietary protection from competitors. Any
patents that we hold may be challenged, circumvented or invalidated by third parties.

Because many patent applications in the United States and certain other jurisdictions are maintained in secrecy for 18 months, and
since publication of discoveries in the scientific or patent literature often lags behind actual discoveries, we cannot be certain that we will be
able to obtain patent protection for the inventions disclosed and/or claimed in our pending patent applications. Moreover, we may have to
participate in interference proceedings declared by the United States Patent and Trademark Office or a foreign patent office to determine
priority of invention or in post grant challenge proceedings, such as oppositions, inter partes review, post grant review or a derivation
proceeding, that challenge our entitlement to an invention or the patentability of one or more claims in our patent applications or issued
patents. Such proceedings could result in substantial cost, even if the eventual outcome is favorable to us.

The term of individual patents depends upon the legal term of the patents in the countries in which they are obtained. In most

countries in which we file, the patent term is 20 years from the earliest date of filing a PCT application or a non-provisional patent
application, subject to any disclaimers or extensions. The term of a patent in the United States can be adjusted and extended due to the
failure of the United States Patent and Trademark Office following certain statutory and regulation deadlines for issuing a patent.

14

 
Table of Contents

In the United States, the patent term of a patent that covers an FDA approved drug also may be eligible for patent term extension,

which permits patent term restoration as compensation for a portion of the patent term lost during clinical development and the FDA
regulatory review process. The Hatch Waxman Act permits a patent term extension of up to five years beyond the expiration of the patent.
The length of the patent term extension is related to the length of time the drug is under clinical development and regulatory review. Patent
term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval and only one
patent applicable to an approved drug may be extended. Similar provisions are available in Europe and other non-United States jurisdictions
to extend the term of a patent that covers an approved drug. In the future, if and when our pharmaceutical products receive FDA approval,
we expect to apply for patent term extensions on patents covering those products. Although, we intend to seek patent term extensions to any
of our issued patents in any jurisdiction where these are available there is no guarantee that the applicable authorities, including the United
States Patent and Trademark Office, will agree with our assessment of whether such extensions should be granted, and even if granted, the
length of such extensions.

We also rely on trade secret protection for our confidential and proprietary information. Although we take steps to protect our

proprietary information and trade secrets, including through contractual means with our employees and consultants, third parties may
independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets or
disclose our technology. Thus, we may not be able to meaningfully protect our trade secrets. It is our policy to require our employees,
consultants, outside scientific collaborators, sponsored researchers and other advisors to execute confidentiality agreements upon the
commencement of employment or consulting relationships with us. These agreements provide that all confidential information concerning
our business or financial affairs developed or made known to the individual during the course of the individual’s relationship with us is to be
kept confidential and not disclosed to third parties except in specific circumstances. In the case of employees, the agreements provide that
all inventions conceived by the individual, and which are related to our current or planned business or research and development or made
during normal working hours, on our premises or using our equipment or proprietary information, are our exclusive property.

Manufacturing

We do not own or operate any manufacturing facilities. We currently rely, and expect to continue to rely, on third parties for the
manufacture of our product candidates for preclinical and clinical testing, as well as for commercial manufacture if our product candidates
receive marketing approval.

Commercialization

We have not yet fully established sales, marketing or product distribution infrastructure. Subject to successfully completing
product development and receiving marketing approvals, we expect to commence commercialization activities for our wholly owned
products by insourcing or outsourcing a sales organization, initially in the hospital market, or by seeking a commercial partner in the United
States. If we choose to insource or outsource a sales organization, we believe that it will be able to address the community of physicians who
are the key specialists in treating the patient populations for which our product candidates are being developed. Outside the United States,
we expect to enter into distribution and other commercial arrangements with third parties for any of our product candidates that obtain
marketing approval. We also intend to license out commercial rights for products that require a substantial primary care presence. In parallel
with building our commercial organization, we plan to develop educational initiatives with respect to approved products and relationships
with thought leaders in relevant fields of medicine.

Competition

The biotechnology and pharmaceutical industries are characterized by rapidly advancing technologies, intense competition and a
strong emphasis on proprietary products. While we believe that our technology, knowledge, experience and scientific resources provide us
with competitive advantages, we face potential competition from many different sources, including major pharmaceutical, specialty
pharmaceutical and biotechnology companies, academic institutions and governmental agencies and public and private research institutions.
Any product candidates that we successfully develop and commercialize will compete with existing therapies and new therapies that may
become available in the future. Products in development by other companies may provide efficacy, safety, convenience and other

15

 
Table of Contents

benefits that are not provided by currently marketed therapies. As a result, they may provide significant competition for any of our product
candidates for which we obtain marketing approval.

Some of the companies against which we are competing or against which we may compete in the future have significantly greater

financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining
regulatory approvals and marketing approved products than we do. Mergers and acquisitions in the pharmaceutical, biotechnology and
diagnostic industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early
stage companies also may prove to be significant competitors, particularly through collaborative arrangements with large and established
companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and
establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary
for, our programs.

The key competitive factors affecting the success of all of our therapeutic product candidates, if approved, are likely to be their

efficacy, safety, convenience, price, the level of generic competition and the availability of reimbursement from government and other third-
party payors.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer,

more effective, have fewer or less severe side effects, are more convenient or are less expensive than any products that we may develop.
Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours,
which could result in our competitors establishing a strong market position before we are able to enter the market. In addition, our ability to
compete may be affected in many cases by insurers or other third-party payors seeking to encourage the use of generic products. Generic
products that broadly address these indications are currently on the market for the indications that we are pursuing, and additional products
are expected to become available on a generic basis over the coming years. If our product candidates achieve marketing approval, we expect
that they will be priced at a significant premium over competitive generic products.

Government Regulation and Product Approval

Government authorities in the United States, at the federal, state and local level, and in other countries extensively regulate, among

other things, the research, development, testing, manufacture, packaging, storage, recordkeeping, labeling, advertising, promotion,
distribution, marketing, import and export of pharmaceutical products such as those we are developing. The processes for obtaining
regulatory approvals in the United States and in foreign countries, along with subsequent compliance with applicable statutes and
regulations, require the expenditure of substantial time and financial resources.

FDA Regulation

In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, and its implementing
regulations. The process of obtaining regulatory approvals and the subsequent compliance with applicable federal, state, local and foreign
statutes and regulations requires the expenditure of substantial time and financial resources. Failure to comply with the applicable United
States requirements at any time during the product development process, approval process or after approval, may subject an applicant to a
variety of administrative or judicial sanctions, such as the FDA’s refusal to approve pending NDAs, withdrawal of an approval, imposition
of a clinical hold, issuance of warning or untitled letters, product recalls, product seizures, total or partial suspension of production or
distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties.

The process required by the FDA before a drug may be marketed in the United States generally involves the following:

·

completion of preclinical laboratory tests, animal studies and formulation studies in compliance with the FDA’s good laboratory
practice, or GLP, regulations;

16

 
Table of Contents

·

·

·

·

·

·

·

·

submission to the FDA of an IND, which must become effective before human clinical trials may begin;

approval by an independent institutional review board, or IRB, covering each clinical site before each trial may be initiated;

performance of human clinical trials, including adequate and well‑controlled clinical trials, in accordance with good clinical
practices, or GCP, to establish the safety and efficacy of the proposed drug product for each indication;

submission of an NDA to the FDA;

completion of an FDA advisory committee review, if applicable;

satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the product is produced to assess
compliance with cGMP, and to assure that the facilities, methods and controls are adequate to preserve the drug’s identity,
strength, quality and purity, as well as satisfactory completion of an FDA inspection of selected clinical sites to determine GCP
compliance;

FDA review and approval of an NDA; and

in certain cases, DEA review and scheduling activities prior to launch.

Preclinical Studies

Preclinical studies include laboratory evaluation of drug substance chemistry, toxicity and drug product formulation, as well as

animal studies to assess potential safety and efficacy. An IND sponsor must submit the results of the preclinical tests, together with
manufacturing information, analytical data and any available clinical data or literature, among other things, to the FDA as part of an IND.
Manufacture of drug substance, drug product and the labeling and distribution of clinical supplies must all comply with cGMP standards.
Some preclinical testing may continue even after the IND is submitted. An IND automatically becomes effective 30 days after receipt by the
FDA, unless before that time the FDA raises concerns or questions related to the data submitted in the IND or the proposed clinical trials and
places the trial on a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical
trial can begin. As a result, submission of an IND may not result in the FDA allowing clinical trials to commence.

Clinical Trials

Clinical trials involve the administration of the investigational new drug to human subjects under the supervision of qualified

investigators in accordance with GCP requirements, which include the requirement that all research subjects provide their informed consent
in writing for their participation in any clinical trial. Clinical trials are conducted under protocols detailing, among other things, the
objectives of the trial, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. A protocol for each
clinical trial and any subsequent protocol amendments must be submitted to the FDA as part of the IND. In addition, an IRB covering each
institution participating in the clinical trial must review and approve the plan for any clinical trial before it commences at that institution,
and the IRB must continue to oversee the clinical trial while it is being conducted. Information about certain clinical trials must be
submitted within specific timeframes to the National Institutes of Health, or NIH, for public dissemination on their ClinicalTrials.gov
website.

Human clinical trials are typically conducted in three sequential phases, which may overlap or be combined. In Phase 1, the drug is

initially introduced into healthy human subjects or patients with the target disease or condition and tested for safety, dosage tolerance,
absorption, metabolism, distribution, excretion and, if possible, to gain an initial indication of its effectiveness. In Phase 2, the drug
typically is administered to a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the
efficacy of the product for specific targeted

17

 
Table of Contents

diseases and to determine dosage tolerance and optimal dosage. In Phase 3, the drug is administered to an expanded patient population,
generally at geographically dispersed clinical trial sites, in well‑controlled clinical trials to generate enough data to statistically evaluate the
efficacy and safety of the product for approval, to establish the overall risk‑benefit profile of the product and to provide adequate
information for the labeling of the product.

Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and more frequently if

serious adverse events occur. Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, or
at all. Furthermore, the FDA or the sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that
the research subjects are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial
at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the drug has been associated with
unexpected serious harm to patients.

Marketing Approval

Assuming successful completion of the required clinical testing, the results of the preclinical and clinical studies, together with

detailed information relating to the product’s chemistry, manufacture, controls and proposed labeling, among other things, are submitted to
the FDA as part of an NDA requesting approval to market the product for one or more indications. In most cases, the submission of an NDA
is subject to a substantial application user fee. Under the Prescription Drug User Fee Act, or PDUFA, guidelines that are currently in effect,
the FDA has agreed to certain performance goals regarding the timing of its review of a marketing application.

In addition, under the Pediatric Research Equity Act an NDA or supplement to an NDA must contain data that are adequate to

assess the safety and effectiveness of the drug for the claimed indications in all relevant pediatric subpopulations, and to support dosing and
administration for each pediatric subpopulation for which the product is safe and effective. The FDA may, on its own initiative or at the
request of the applicant, grant deferrals for submission of some or all pediatric data until after approval of the product for use in adults, or
full or partial waivers from the pediatric data requirements.

The FDA also may require a risk evaluation and mitigation strategy, or REMS, to mitigate any identified or suspected serious risks

and ensure safe use of the drug. The REMS plan could include medication guides, physician communication plans, assessment plans and
elements to assure safe use, such as restricted distribution methods, patient registries or other risk minimization tools. We expect that the
mu‑opioid agonist products may be subject to a REMS, since currently marketed opioid products are subject to this requirement.

The FDA conducts a preliminary review of all NDAs within the first 60 days after submission, before accepting them for filing, to

determine whether they are sufficiently complete to permit substantive review. The FDA may request additional information rather than
accept an NDA for filing. In this event, the application must be resubmitted with the additional information. The resubmitted application is
also subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in‑depth
substantive review. The FDA reviews an NDA to determine, among other things, whether the drug is safe and effective and whether the
facility in which it is manufactured, processed, packaged or held meets standards designed to assure the product’s continued safety, quality
and purity.

The FDA typically refers a question regarding a novel drug to an external advisory committee. An advisory committee is a panel of

independent experts, including clinicians and other scientific experts, that reviews, evaluates and provides a recommendation as to whether
the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee,
but it considers such recommendations carefully when making decisions.

Before approving an NDA, the FDA typically will inspect the facility or facilities where the product is manufactured, referred to as

a Pre‑Approval Inspection, or PAI. The FDA will not approve an application unless it determines that the manufacturing processes and
facilities are in compliance with cGMP requirements and adequate to

18

 
Table of Contents

assure consistent production of the product within required specifications. Additionally, before approving an NDA, the FDA will typically
inspect one or more clinical trial sites to assure compliance with GCPs.

The testing and approval process for an NDA requires substantial time, effort and financial resources, and each may take
several years to complete. Data obtained from preclinical and clinical testing are not always conclusive and may be susceptible to varying
interpretations, which could delay, limit or prevent regulatory approval. The FDA may not grant approval of an NDA on a timely basis, or at
all.

After evaluating the NDA and all related information, including the advisory committee recommendation, if any, and inspection
reports regarding the manufacturing facilities and clinical trial sites, the FDA may issue an approval letter, or, in some cases, a complete
response letter. A complete response letter generally contains a statement of specific conditions that must be met in order to secure final
approval of the NDA and may require additional clinical or preclinical testing in order for the FDA to reconsider the application. Even with
submission of this additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for
approval. If and when those conditions have been met to the FDA’s satisfaction, the FDA will typically issue an approval letter. The FDA
reviews NDA resubmissions in two or six months depending on the type of information included An approval letter authorizes commercial
distribution and marketing of the drug with specific prescribing information for specific indications. For some products, an additional step
of DEA review and scheduling is required.

Even if the FDA approves a product, it may limit the approved indications for use of the product, require that contraindications,

warnings or precautions be included in the product labeling, including a boxed warning, require that post‑approval studies, including
Phase 4 clinical trials, be conducted to further assess a drug’s safety after approval, require testing and surveillance programs to monitor the
product after commercialization or impose other conditions, including distribution restrictions or other risk management mechanisms under
a REMS which can materially affect the potential market and profitability of the product. The FDA may prevent or limit further marketing
of a product based on the results of post‑marketing studies or surveillance programs. After approval, some types of changes to the approved
product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further testing requirements
and FDA review and approval.

Expedited Review and Approval

The FDA has various programs, including Fast Track, Breakthrough Therapy designation, priority review, and accelerated
approval, that are intended to expedite or simplify the process for reviewing drugs, and/or provide for the approval of a drug on the basis of a
surrogate endpoint. Even if a drug qualifies for one or more of these programs, the FDA may later decide that the drug no longer meets the
conditions for qualification or that the time period for FDA review or approval will be shortened. Generally, drugs that are eligible for these
programs are those for serious or life‑threatening conditions, those with the potential to address unmet medical needs and those that offer
meaningful benefits over existing treatments. For example, Fast Track is a process designed to facilitate the development and expedite the
review of drugs to treat serious or life‑threatening diseases or conditions and fill unmet medical needs. Priority review is designed to give
drugs that offer major advances in treatment or provide a treatment where no adequate therapy exists an initial review within six months as
compared to a standard review time of ten months.

Although Fast Track and priority review do not affect the standards for approval, the FDA will attempt to facilitate early and

frequent meetings with a sponsor of a Fast Track designated drug and expedite review of the application for a drug designated for priority
review. Accelerated approval, which is described in Subpart H of 21 Code of Federal Regulations, or 21 CFR Part 314, provides for an
earlier approval for a new drug that is intended to treat a serious or life‑threatening disease or condition and that fills an unmet medical need
based on a surrogate endpoint. A surrogate endpoint is a clinical measurement or other biomarker used as an indirect or substitute
measurement to predict a clinically meaningful outcome. As a condition of approval, the FDA may require that a sponsor of a product
candidate receiving accelerated approval perform post‑marketing clinical trials.

A Breakthrough Therapy designation is intended to expedite the development and FDA review of drugs for serious or

life‑threatening conditions or where preliminary clinical evidence indicates that the drug may demonstrate

19

 
Table of Contents

substantial improvement on a clinically significant endpoint(s) over available therapies. A request for Breakthrough Therapy designation
should be submitted concurrently with, or as an amendment to an IND.

Post‑Approval Requirements

Drugs manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA,

including, among other things, requirements relating to recordkeeping, periodic reporting, product sampling and distribution, advertising
and promotion and reporting of adverse experiences with the product. After approval, most changes to the approved product, such as adding
new indications or other labeling claims are subject to prior FDA review and approval. There also are continuing, annual program user fee
requirements, as well as new application fees for supplemental applications with clinical data.

The FDA may impose a number of post‑approval requirements as a condition of approval of an NDA. For example, the FDA may

require post‑marketing testing, including clinical trials in pediatric patients or other Phase 4 trials, and surveillance to further assess and
monitor the product’s safety and effectiveness after commercialization.

In addition, drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are required to
register their establishments with the FDA and state agencies, and are subject to periodic unannounced inspections by the FDA and these
state agencies for compliance with cGMP requirements. Changes to the manufacturing process are strictly regulated and often require prior
FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and
impose reporting and documentation requirements upon the sponsor and any third-party manufacturers that the sponsor may decide to use.
Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain cGMP
compliance.

Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory requirements and standards is not

maintained or if problems occur after the product reaches the market.

Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency,

or with manufacturing processes, or failure to comply with regulatory requirements, may result in mandatory revisions to the approved
labeling to add new safety information; imposition of post‑marketing studies or clinical trials to assess new safety risks; or imposition of
distribution or other restrictions under a REMS program. Other potential consequences include, among other things:

·

·

·

·

·

restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product
recalls;

fines, warning letters or holds on post‑approval clinical trials;

refusal of the FDA to approve pending NDAs or supplements to approved NDAs, or suspension or revocation of product license
approvals;

product seizure or detention, or refusal to permit the import or export of products; or

injunctions or the imposition of civil or criminal penalties.

The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Although

physicians, in the practice of medicine, may prescribe approved drugs for unapproved indications, pharmaceutical companies generally are
required to promote their drug products only for the approved indications and in accordance with the provisions of the approved label.
However, companies may share truthful and not misleading information that is otherwise consistent with a product’s approved labeling The
FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off‑label uses, and a company that is found
to have improperly promoted off‑label uses may be subject to significant liability.

20

 
Table of Contents

In addition, the distribution of prescription pharmaceutical products is subject to the Prescription Drug Marketing Act, or PDMA,

which regulates the distribution of drugs and drug samples at the federal level, and sets minimum standards for the registration and
regulation of drug distributors by the states. Both the PDMA and state laws limit the distribution of prescription pharmaceutical product
samples and impose requirements to ensure accountability in distribution.

DEA Regulation

Both oliceridine and TRV734, if approved, will be regulated as a “controlled substance” as defined in the Controlled Substances

Act of 1970, or CSA, which establishes registration, security, recordkeeping, reporting, storage, distribution and other requirements
administered by the DEA. The DEA is concerned with the control of handlers of controlled substances, and with the equipment and raw
materials used in their manufacture and packaging, in order to prevent loss and diversion into illicit channels of commerce.

The DEA regulates controlled substances as Schedule I, II, III, IV or V substances. Schedule I substances by definition have no

established medicinal use, and may not be marketed or sold in the United States. A pharmaceutical product may be listed as
Schedule II, III, IV or V, with Schedule II substances considered to present the highest risk of abuse and Schedule V substances the lowest
relative risk of abuse among such substances. Oliceridine and TRV734, if approved, are expected to be listed by the DEA as Schedule II
controlled substances under the CSA. Consequently, their manufacture, shipment, storage, sale and use will be subject to a high degree of
regulation.

Annual registration is required for any facility that manufactures, distributes, dispenses, imports, exports, or conducts research with

any controlled substance. The registration is specific to the particular location, activity and controlled substance schedule. For example,
separate registrations are needed for import and manufacturing, and each registration will specify which schedules of controlled substances
are authorized.

The DEA typically inspects a facility to review its security measures prior to issuing a registration. Security requirements vary by
controlled substance schedule, with the most stringent requirements applying to Schedule I and Schedule II substances. Required security
measures include background checks on employees and physical control of inventory through measures such as cages, surveillance cameras
and inventory reconciliations. Records must be maintained for the handling of all controlled substances, and periodic reports made to the
DEA, for example distribution reports for Schedule I and II controlled substances, Schedule III substances that are narcotics, and other
designated substances. Reports must also be made for thefts or losses of any controlled substance, and to obtain authorization to destroy any
controlled substance. In addition, special authorization and notification requirements apply to imports and exports.

In addition, a DEA quota system controls and limits the availability and production of controlled substances in Schedule I or II.
Distributions of any Schedule I or II controlled substance must also be accompanied by special order forms, with copies provided to the
DEA. The DEA may adjust aggregate production quotas and individual production and procurement quotas from time to time during
the year, although the DEA has substantial discretion in whether or not to make such adjustments. Our, or our contract manufacturers’,
quota of an active ingredient may not be sufficient to meet commercial demand or complete clinical trials. Any delay or refusal by the DEA
in establishing our, or our contract manufacturers’, quota for controlled substances could delay or stop our clinical trials or product launches.

To meet its responsibilities, the DEA conducts periodic inspections of registered establishments that handle controlled substances.
Individual states also regulate controlled substances, and we and our contract manufacturers will be subject to state regulation with respect
to the distribution of these products.

Federal and State Fraud and Abuse and Data Privacy and Security Laws and Regulations

In addition to FDA restrictions on marketing of pharmaceutical products, federal and state fraud and abuse laws restrict business

practices in the biopharmaceutical industry. These laws include anti‑kickback and false claims laws and regulations, as well as transparency
and data privacy and security laws and regulations.

21

 
Table of Contents

The federal Anti‑Kickback Statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving
remuneration to induce or in return for purchasing, leasing, ordering or arranging for or recommending the purchase, lease or order of any
item or service reimbursable under Medicare, Medicaid or other federal healthcare programs. The term “remuneration” has been broadly
interpreted to include anything of value. The federal Anti‑Kickback Statute has been interpreted to apply to arrangements between
pharmaceutical manufacturers on one hand and prescribers, purchasers, formulary managers, and others on the other hand. Although there
are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution, the exceptions and
safe harbors are drawn narrowly and require strict compliance to offer protection. Practices that involve remuneration that may be alleged to
be intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not qualify for an exception or safe
harbor. Several courts have interpreted the statute’s intent requirement to mean that if any one purpose of an arrangement involving
remuneration is to induce referrals of federal healthcare covered business, the statute has been violated.

The reach of the federal Anti‑Kickback Statute was also broadened by the Patient Protection and Affordable Care Act of 2010, as

amended by the Health Care and Education Reconciliation Act of 2010, or collectively PPACA, which, among other things, amended the
intent requirement of the federal Anti‑Kickback Statute such that a person or entity no longer needs to have actual knowledge of this statute
or specific intent to violate it in order to have committed a violation. In addition, PPACA provides that the government may assert that a
claim including items or services resulting from a violation of the federal Anti‑Kickback Statute constitutes a false or fraudulent claim for
purposes of the federal False Claims Act or the civil monetary penalties statute, which imposes penalties against any person who is
determined to have presented or caused to be presented a claim to a federal health program that the person knows or should know is for an
item or service that was not provided as claimed or is false or fraudulent. PPACA also created new federal requirements for reporting, by
applicable manufacturers of covered drugs of payments and other transfers of value to, as well as ownership interests held by, physicians
and teaching hospitals.

The federal criminal and civil false claims laws and civil monetary penalties laws, including the federal False Claims Act, prohibit

any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government or knowingly
making, using or causing to be made or used a false record or statement material to a false or fraudulent claim to the federal government. A
claim includes “any request or demand” for money or property presented to the U.S. government. Several pharmaceutical and other
healthcare companies have been prosecuted under these laws for allegedly providing free product to customers with the expectation that the
customers would bill federal programs for the product. Other companies have been prosecuted for causing false claims to be submitted
because of the companies’ marketing of products for unapproved, and thus non‑reimbursable, uses.

The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, created additional federal civil and criminal
statutes that prohibit knowingly and willfully executing a scheme to defraud any healthcare benefit program, including private third-party
payors and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or
fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Also, many states have similar
fraud and abuse statutes or regulations that apply to items and services reimbursed under Medicaid and other state programs, or, in several
states, apply regardless of the payor.

In addition, we may be subject to data privacy and security regulation by both the federal government and the states in which we
conduct our business. HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and
their respective implementing regulations, including the final omnibus rule published on January 25, 2013, imposed specified requirements
relating to the privacy, security and transmission of individually identifiable health information on "covered entities," including certain
healthcare providers, health plans, and healthcare clearinghouses. Among other things, HITECH makes HIPAA’s privacy and security
standards directly applicable to “business associates,” defined as independent contractors or agents of covered entities that create, receive,
maintain or transmit protected health information in connection with providing a service for or on behalf of a covered entity. HITECH also
increased the civil and criminal penalties that may be imposed against covered entities, business associates and possibly other persons, and
gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws
and seek attorney’s fees and costs associated with pursuing federal civil actions. In addition, state laws govern the privacy and security of
health information in certain

22

 
Table of Contents

circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance
efforts.

Because of the breadth of these laws and the narrowness of available statutory exceptions and regulatory safe harbors, it is possible

that some of our business activities could be subject to challenge under one or more of such laws. If our operations are found to be in
violation of any of the federal or state laws described above or any other governmental regulations that apply to us, we may be subject to
penalties, including significant criminal, civil, and administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from
participation in government healthcare programs, integrity oversight and reporting obligations to resolve allegations of non-compliance with
these laws, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and
our results of operations. To the extent that any of our products are sold in a foreign country, we may be subject to similar foreign laws and
regulations, which may include, for instance, applicable post‑marketing requirements, including safety surveillance, anti‑fraud and abuse
laws, implementation of corporate compliance programs and reporting of payments or transfers of value to healthcare professionals, and
data privacy requirements such as the General Data Protection Regulation (EU) 2016/679.

Coverage and Reimbursement

The commercial success of our product candidates and our ability to commercialize any approved product candidates successfully

will depend in part on the extent to which governmental payor programs at the federal and state levels, including Medicare and Medicaid,
private health insurers and other third-party payors provide coverage for and establish adequate reimbursement levels for our product
candidates. Government health administration authorities, private health insurers and other organizations generally decide which drugs they
will pay for and establish reimbursement levels for healthcare. In particular, in the United States, private health insurers and other third-
party payors often provide reimbursement for products and services based on the level at which the government provides reimbursement
through the Medicare or Medicaid programs for such treatments. In the United States, the European Union and other potentially significant
markets for our product candidates, government authorities and third-party payors are increasingly attempting to limit or regulate the price
of medical products and services, particularly for new and innovative products and therapies, which often has resulted in average selling
prices lower than they would otherwise be. Further, the increased emphasis on managed healthcare in the United States and on country and
regional pricing and reimbursement controls in the European Union will put additional pressure on product pricing, reimbursement and
usage, which may adversely affect our future product sales and results of operations. These pressures can arise from rules and practices of
managed care groups, judicial decisions and governmental laws and regulations related to Medicare, Medicaid and healthcare reform,
pharmaceutical coverage and reimbursement policies and pricing in general.

Third-party payors are increasingly imposing additional requirements and restrictions on coverage and limiting reimbursement

levels for medical products. For example, in the United States, federal and state governments reimburse covered prescription drugs at
varying rates generally below average wholesale price. These restrictions and limitations influence the purchase of healthcare services and
products. Third‑party payors may limit coverage to specific drug products on an approved list, or formulary, which might not include all of
the FDA‑approved drug products for a particular indication. Third-party payors are increasingly challenging the price and examining the
medical necessity and cost‑effectiveness of medical products and services, in addition to their safety and efficacy. We may need to conduct
expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost‑effectiveness of our products, in addition to the
costs required to obtain FDA approvals. Our product candidates may not be considered medically necessary or cost‑effective. A payor’s
decision to provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved. Adequate third-party
reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on our investment in
drug development. In addition, for hospital products, a private health insurer or Medicare will typically reimburse a fixed fee for certain
procedures, including in-patient surgeries. Pharmaceutical products such as oliceridine, if approved, that may be used in connection with the
surgery generally will not be separately reimbursed and, therefore, a hospital would have to assess the cost of oliceridine, if approved,
relative to its benefits. Current or future efforts to limit the level of reimbursement for in-patient hospital procedures could cause a hospital
to decide not to use oliceridine, if approved by the FDA. Legislative proposals to reform healthcare or reduce costs under government
insurance programs may result in lower reimbursement for our

23

 
Table of Contents

products and product candidates or exclusion of our products and product candidates from coverage. The cost containment measures that
healthcare payors and providers are instituting and any healthcare reform could significantly reduce our revenue from the sale of any
approved product candidates. We cannot provide any assurances that we will be able to obtain and maintain third-party coverage or
adequate reimbursement for our product candidates in whole or in part.

Impact of Healthcare Reform on Coverage, Reimbursement and Pricing

The United States and some foreign jurisdictions are considering enacting or have enacted a number of additional legislative and

regulatory proposals to change the healthcare system in ways that could affect our ability to sell our products profitably. Among policy
makers and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated
goals of containing healthcare costs, improving quality and expanding access. In the United States, the pharmaceutical industry has been a
particular focus of these efforts and has been significantly affected by major legislative initiatives. For example, the Medicare Prescription
Drug, Improvement, and Modernization Act of 2003, or the MMA, imposed new requirements for the distribution and pricing of
prescription drugs for Medicare beneficiaries. Under Part D, Medicare beneficiaries may enroll in prescription drug plans offered by private
entities that provide coverage of outpatient prescription drugs. Part D plans include both standalone prescription drug benefit plans and
prescription drug coverage as a supplement to Medicare Advantage plans. Unlike Medicare Part A and B, Part D coverage is not
standardized. Part D prescription drug plan sponsors are not required to pay for all covered Part D drugs, and each drug plan can develop its
own drug formulary that identifies which drugs it will cover and at what tier or level. However, Part D prescription drug formularies must
include drugs within each therapeutic category and class of covered Part D drugs, though not necessarily all the drugs in each category or
class. Any formulary used by a Part D prescription drug plan must be developed and reviewed by a pharmacy and therapeutic committee.
Government payment for some of the costs of prescription drugs may increase demand for any products for which we receive marketing
approval. However, any negotiated prices for our future products covered by a Part D prescription drug plan will likely be lower than the
prices we might otherwise obtain. Moreover, while the MMA applies only to drug benefits for Medicare beneficiaries, private payors often
follow Medicare coverage policy and payment limitations in setting their own payment rates. Any reduction in payment that results from
Medicare Part D may result in a similar reduction in payments from non‑governmental payors.

The American Recovery and Reinvestment Act of 2009 provides funding for the federal government to compare the effectiveness
of different treatments for the same illness. A plan for the research will be developed by the Department of Health and Human Services, or
HHS, the Agency for Healthcare Research and Quality and the National Institutes of Health, and periodic reports on the status of the
research and related expenditures will be made to Congress. Although the results of the comparative effectiveness studies are not intended to
mandate coverage policies for public or private payors, it is not clear what effect, if any, the research will have on the sales of any product, if
any such product or the condition that it is intended to treat is the subject of a study. It is also possible that comparative effectiveness
research demonstrating benefits in a competitor’s product could adversely affect the sales of our product candidates. If third-party payors do
not consider our product candidates to be cost‑effective compared to other available therapies, they may not cover our product candidates,
once approved, as a benefit under their plans or, if they do, the level of payment may not be sufficient to allow us to sell our products on a
profitable basis.

PPACA became law in March 2010 and substantially changes the way healthcare is financed by both governmental and private

insurers. Among other cost containment measures, the PPACA established an annual, nondeductible fee on any entity that manufactures or
imports specified branded prescription drugs and biologic agents; a new Medicare Part D coverage gap discount program; and a new
formula that increased the rebates a manufacturer must pay under the Medicaid Drug Rebate Program. In the years since its enactment, there
have been, and continue to be, significant developments in, and continued judicial, executive branch, and legislative activity around,
attempts to repeal or repeal and replace the PPACA. On December 14, 2018, a Texas U.S. District Court Judge ruled that the PPACA is
unconstitutional in its entirety because the “individual mandate,” the tax-based shared responsibility payment on certain individuals who fail
to maintain qualifying health coverage for all or part of a year, was repealed by Congress as part of the Tax Cuts and Jobs Act of 2017.
While the Texas U.S. District Court Judge, as well as the current Presidential administration and the Centers for Medicare & Medicaid
Services, or CMS, have stated that the ruling will have no immediate effect pending appeal of the decision, it is unclear how this decision,
subsequent appeals, and other efforts to

24

 
Table of Contents

repeal and replace the PPACA will impact the PPACA. In the future, there may continue to be additional proposals relating to the reform of
the U.S. healthcare system, some of which could further limit the prices we are able to charge for our product candidates, once approved, or
the amounts of reimbursement available for our product candidates once they are approved.

In addition, other legislative changes have been proposed and adopted since PPACA was enacted. In August 2011, the Budget

Control Act of 2011, as amended, was signed into law. Among other things, this law created the Joint Select Committee on Deficit
Reduction to propose spending reductions to Congress. The Joint Select Committee on Deficit Reduction did not achieve its targeted deficit
reduction of at least $1.2 trillion for the years 2013 through 2021, triggering the legislation’s automatic reductions to several government
programs. These reductions include aggregate reductions to Medicare payments to providers of 2% per fiscal year, which went into effect on
April 1, 2013, and, due to subsequent legislative amendments, will remain in effect through 2027 unless additional Congressional action is
taken. In January 2013, the American Taxpayer Relief Act of 2012 became law, which, among other things, further reduced Medicare
payments to several providers and increased the statute of limitations period for the government to recover overpayments to providers from
three to five years.

Further, there has been heightened governmental scrutiny in the United States of pharmaceutical pricing practices in light of the

rising cost of prescription drugs and biologics. Such scrutiny has resulted in several recent Congressional inquiries and proposed and
enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship
between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for products. At the
federal level, the Trump administration released a “Blueprint” to lower drug prices and reduce out of pocket costs of drugs that contains
additional proposals to increase manufacturer competition, increase the negotiating power of certain federal healthcare programs,
incentivize manufacturers to lower the list price of their products and reduce the out of pocket costs of drug products paid by consumers. For
example, in September 2018, CMS announced that it will allow Medicare Advantage Plans the option to use step therapy for Part B drugs
beginning January 1, 2019. On January 31, 2019, the HHS Office of Inspector General proposed modifications to the federal Anti-Kickback
Statute discount safe harbor for the purpose of reducing the cost of drug products to consumers which, among other things, if finalized, will
affect discounts paid by manufacturers to Medicare Part D plans, Medicaid managed care organizations and pharmacy benefit managers
working with these organizations. While some of these and other proposed measures may require additional authorization to become
effective, Congress and the Trump administration have each indicated that it will continue to seek new legislative and/or administrative
measures to control drug costs These and other healthcare reform initiatives may result in additional reductions in Medicare and other
healthcare funding. We cannot anticipate what impact these or other future healthcare reform initiatives will have on coverage and
reimbursement of our products or our business more generally.

Exclusivity and Approval of Competing Products

Hatch‑Waxman Patent Exclusivity

In seeking approval for a drug through an NDA, applicants are required to list with the FDA each patent with claims that cover the

applicant’s product or a method of using the product. Upon approval of a drug, each of the patents listed in the application for the drug is
then published in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book.
Drugs listed in the Orange Book can, in turn, be cited by potential competitors in support of approval of an abbreviated new drug
application, or ANDA, or 505(b)(2) NDA. Generally, an ANDA provides for marketing of a drug product that has the same active
ingredients in the same strengths, dosage form and route of administration as the listed drug and has been shown to be bioequivalent through
in vitro and/or in vivo testing or otherwise to the listed drug. ANDA applicants are not required to conduct or submit results of preclinical or
clinical tests to prove the safety or effectiveness of their drug product, other than the requirement for bioequivalence testing. Drugs approved
in this way are commonly referred to as “generic equivalents” to the listed drug, and can often be substituted by pharmacists under
prescriptions written for the original listed drug. 505(b)(2) NDAs generally are submitted for changes to a previously approved drug
product, such as a new dosage, dosage form, or indication.

25

 
Table of Contents

The ANDA or 505(b)(2) NDA applicant is required to certify to the FDA concerning any patents listed for the approved product in

the FDA’s Orange Book, except for patents covering methods of use for which the ANDA applicant is not seeking approval. Specifically,
the applicant must certify with respect to each patent that:

·

·

·

·

the required patent information has not been filed;

the listed patent has expired;

the listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration; or

the listed patent is invalid, unenforceable or will not be infringed by the new product.

Generally, the ANDA or 505(b)(2) NDA cannot be approved until all listed patents have expired, except when the ANDA or

505(b)(2) NDA applicant challenges a patent of a listed drug. A certification that the proposed product will not infringe the already
approved product’s listed patents or that such patents are invalid or unenforceable is called a Paragraph IV certification. If the applicant does
not challenge the listed patents or indicate that it is not seeking approval of a patented method of use, the ANDA or 505(b)(2) NDA
application will not be approved until all the listed patents claiming the referenced product have expired.

If the ANDA or 505(b)(2) NDA applicant has provided a Paragraph IV certification to the FDA, the applicant must also send

notice of the Paragraph IV certification to the NDA and patent holders once the application has been accepted for filing by the FDA. The
NDA and patent holders may then initiate a patent infringement lawsuit in response to the notice of the Paragraph IV certification. The filing
of a patent infringement lawsuit within 45 days after the receipt of notice of the Paragraph IV certification automatically prevents the FDA
from approving the ANDA or 505(b)(2) NDA until the earlier of 30 months, expiration of the patent, settlement of the lawsuit or a decision
in the infringement case that is favorable to the ANDA applicant.

Hatch‑Waxman Non‑Patent Exclusivity

Market and data exclusivity provisions under the FDCA also can delay the submission or the approval of certain applications for
competing products. The FDCA provides a five‑year period of non‑patent data exclusivity within the United States to the first applicant to
gain approval of an NDA for a new chemical entity. A drug is a new chemical entity if the FDA has not previously approved any other new
drug containing the same active moiety, which is the molecule or ion responsible for the activity of the drug substance. During the
exclusivity period, the FDA may not accept for review an ANDA or a 505(b)(2) NDA submitted by another company that contains the
previously approved active moiety. However, an ANDA or 505(b)(2) NDA may be submitted after four years if it contains a certification of
patent invalidity or noninfringement. The FDCA also provides three years of marketing exclusivity for an NDA, 505(b)(2) NDA, or
supplement to an existing NDA or 505(b)(2) NDA if new clinical investigations, other than bioavailability studies, that were conducted or
sponsored by the applicant, are deemed by the FDA to be essential to the approval of the application or supplement. Three‑year exclusivity
may be awarded for changes to a previously approved drug product, such as new indications, dosages, strengths or dosage forms of an
existing drug. This three‑year exclusivity covers only the conditions of use associated with the new clinical investigations and, as a general
matter, does not prohibit the FDA from approving ANDAs or 505(b)(2) NDAs for generic versions of the original, unmodified drug
product. Five‑year and three‑year exclusivity will not delay the submission or approval of a full NDA; however, an applicant submitting a
full NDA would be required to conduct or obtain a right of reference to all of the preclinical studies and adequate and well‑controlled
clinical trials necessary to demonstrate safety and effectiveness.

Pediatric Exclusivity

Pediatric exclusivity is another type of non‑patent marketing exclusivity in the United States and, if granted, provides for the

attachment of an additional six months of marketing protection to the term of any existing regulatory exclusivity, including the non‑patent
exclusivity periods described above. This six‑month exclusivity may be granted if an NDA sponsor submits pediatric data that fairly
respond to a written request from the FDA for such data. The data do

26

 
Table of Contents

not need to show the product to be effective in the pediatric population studied; rather, if the clinical trial is deemed to fairly respond to the
FDA’s request, the additional protection is granted. If reports of requested pediatric studies are submitted to and accepted by the FDA within
the statutory time limits, whatever statutory or regulatory periods of exclusivity or Orange Book listed patent protection cover the drug are
extended by six months. This is not a patent term extension, but it effectively extends the regulatory period during which the FDA cannot
approve an ANDA or 505(b)(2) application owing to regulatory exclusivity or listed patents. When any of our products is approved, we
anticipate seeking pediatric exclusivity when it is appropriate.

Foreign Regulation

To market any product outside of the United States, we would need to comply with numerous and varying regulatory requirements
of other countries regarding safety and efficacy and governing, among other things, clinical trials, marketing authorization, commercial sales
and distribution of our products. For example, in the European Union, we must obtain authorization of a clinical trial application, or CTA, in
each member state in which we intend to conduct a clinical trial. Whether or not we obtain FDA approval for a product, we would need to
obtain the necessary approvals by the comparable regulatory authorities of foreign countries before we can commence clinical trials or
marketing of the product in those countries. The approval process varies from country to country and can involve additional product testing
and additional administrative review periods. The time required to obtain approval in other countries might differ from and be longer than
that required to obtain FDA approval. Regulatory approval in one country does not ensure regulatory approval in another, but a failure or
delay in obtaining regulatory approval in one country may negatively impact the regulatory process in others.

Employees

As of December 31, 2018, we had 29 employees, all of whom are located in the United States. None of our employees are
represented by a labor union or covered by a collective bargaining agreement. We consider our relationship with our employees to be good.

ITEM 1A. RISK FACTORS 

Our business is subject to numerous risks. You should carefully consider the following risks and all other information contained in
this Annual Report on Form 10‑K, as well as general economic and business risks, together with any other documents we file with the SEC.
If any of the following events actually occur or risks actually materialize, it could have a material adverse effect on our business, operating
results and financial condition and cause the trading price of our common stock to decline.

Risks Related to Our Financial Position and Capital Needs

We have incurred significant losses since our inception. We expect to incur losses over the next several years and may never achieve or
maintain profitability.

Since inception, we have incurred significant operating losses. Our net loss was $30.8 million, $71.9 million, and $103.0 million
for the years ended December 31, 2018, 2017, and 2016, respectively. As of December 31, 2018, we had an accumulated deficit of $388.3
million. To date, we have financed our operations primarily through private placements and public offerings of our equity securities and
debt borrowings. We have devoted substantially all of our financial resources and efforts to research and development, including nonclinical
studies and clinical trials. We still have not completed development of any of our product candidates. We expect to continue to incur
significant expenses and operating losses over the next several years. Our net losses may fluctuate significantly from quarter to quarter and
year to year. We anticipate that our expenses will increase as we:

·

·

·

·

conduct any additional clinical trials with oliceridine to generate data needed to satisfy the FDA’s CRL and/or conduct clinical
trials for TRV250 or our other product candidates;

seek to identify additional product candidates;

conduct clinical trials and seek regulatory approvals for any product candidates that successfully complete clinical trials;

establish sales, marketing and distribution capabilities and scale up external manufacturing capabilities to commercialize
oliceridine, if approved, and any other products that we choose not to license to a third party and for which we may obtain
regulatory approval;

· maintain, expand, and protect our intellectual property portfolio;

29

 
Table of Contents

·

·

·

hire additional sales, marketing, medical, clinical and scientific personnel;

defend the Company in the existing class action and stockholder derived litigation; and

add operational, financial, and management information systems and personnel, including personnel to support our product
development and planned future commercialization efforts.

To become and remain profitable, we must succeed in raising substantial additional funding for the Company and developing and

eventually commercializing products that generate significant revenue. This will require us to be successful in a range of challenging
activities, including completing nonclinical testing and clinical trials of our product candidates, identifying additional product candidates,
potentially entering into collaboration and license agreements, obtaining regulatory approval for product candidates, and manufacturing,
marketing, and selling any products for which we may obtain regulatory approval. We are only in the preliminary stages of some of these
activities and have not begun others. We may never succeed in these activities and, even if we do, may never achieve profitability.

Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to accurately

predict the timing or amount of increased expenses, whether we will have sufficient funding available to or when, or if, we will be able to
achieve profitability. If we are required by the FDA or foreign regulatory authorities to perform studies in addition to those currently
anticipated as part of the CRL, or if there are any delays in completing our clinical trials, making necessary regulatory filings, or the
development of any of our product candidates, our expenses could increase. Absent substantial additional fundraising, the level and extent
of our clinical and, if approved, commercial efforts may lead to a delay in our ability to achieve profitability.

Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our

failure to become and remain profitable would depress the value of our company and could impair our ability to raise capital, expand our
business, continue our development efforts, diversify our product offerings, or even continue our operations. A decline in the value of our
company also could cause you to lose all or part of your investment.

We will need substantial additional funding, which may not be available to us on acceptable terms, or at all. If we are unable to raise
capital when needed, we could be forced to delay, reduce or eliminate our product development programs or commercialization efforts.

Over the next several years, we expect to incur significant expenses in connection with our current operations and the servicing and

repayment of our outstanding debt obligations. Accordingly, we will need to obtain substantial additional funding for these efforts and for
the continued repayment of our outstanding term loans through the March 2020 maturity date; we would seek to obtain this funding through
the sale of equity, the incurrence of debt, and/or other sources, including potential collaborations. Ultimately, we may be unable to raise
additional funds or enter into such other arrangements when needed, on favorable terms, or at all. If we fail to raise additional capital or enter
into such arrangements as, and when, needed, we could be forced to:

·

·

·

·

significantly delay, scale back, or discontinue our operations, development programs, and/or any future commercialization
efforts;

relinquish, or license on unfavorable terms, our rights to technologies or product candidates that we otherwise would seek to
develop or commercialize ourselves;

seek collaborators for one or more of our product candidates at an earlier stage than otherwise would be desirable or on terms that
are less favorable than might otherwise be available; or

cease operations altogether.

30

 
Table of Contents

We estimate that our existing cash and cash equivalents and marketable securities as of December 31, 2018, together with interest
thereon, and after giving effect to the restructuring described herein, to be sufficient to fund our operating expenses and capital expenditure
requirements into the third quarter of 2020. If we are unable to raise additional funds prior to this date, or we do not take steps to reduce our
expenses, our lenders may conclude that there has been a material adverse change in our financial condition, or a material impairment in the
value of the loan collateral or in the prospect of repayment of our obligations to the lenders. In this case, the lenders have the right to
foreclose on the available collateral, including our cash and cash equivalents and marketable securities.

The extent of our future capital requirements will depend on many factors, including:

the scope, progress, results and costs of nonclinical development, laboratory testing, and clinical trials for our product candidates,
including oliceridine and TRV250;

the number and development requirements of other product candidates that we pursue;

the costs, timing, and outcome of regulatory review of any product candidates, both in the United States and in territories outside
the United States;

the costs and timing of future commercialization activities, including product manufacturing, marketing, sales, and distribution,
for any of our product candidates for which we receive marketing approval;

the revenue, if any, received from commercial sales of our product candidates for which we receive marketing approval;

our ability to enter into collaborative agreements for the development and commercialization of our product candidates, including
oliceridine;

any product liability or other lawsuits related to our products or operations;

the expenses needed to attract and retain skilled personnel; and

the costs involved in preparing, filing, and prosecuting patent applications, maintaining and enforcing our intellectual property
rights, and defending any intellectual property-related claims, both in the United States and in territories outside the United States.

·

·

·

·

·

·

·

·

·

Identifying potential product candidates and conducting nonclinical testing and clinical trials is a time-consuming, expensive and
uncertain process that takes years to complete. Despite these efforts, we may never generate the necessary data or results required to obtain
regulatory approval and achieve product sales. In addition, our product candidates, if approved, may not achieve commercial success or
meet our expectations. Our commercial revenue, if any, will be derived from sales of products that we do not expect to be commercially
available for the foreseeable future, if at all. Accordingly, we will need to continue to rely on additional financing to achieve our business
objectives. Adequate additional financing may not be available to us on acceptable terms, or at all. In addition, we may seek additional
capital due to favorable market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future
operating plans.

Raising additional capital may cause dilution to our stockholders, restrict our operations, or require us to relinquish rights to our
technologies or product candidates.

Until such time, if ever, as we can generate substantial product revenue and positive cash flows from operations, we expect to

finance our cash needs through a combination of equity offerings, debt financings, and license and development agreements in connection
with any collaborations. We do not have any committed external source of funds. To the extent that we raise additional capital through the
sale of equity or convertible debt securities, your ownership interest will be diluted, either at the time of such capital raise or thereafter, and
the terms of these securities

31

 
Table of Contents

may include liquidation or other preferences that adversely affect your rights as a common stockholder. Preferred equity financing and
additional debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific
actions, such as incurring additional debt, making capital expenditures, or declaring dividends, or that include covenants requiring us to
meet certain obligations, such as minimum cash requirements or net revenue targets.

If we raise additional funds through collaborations, strategic alliances, or marketing, distribution or licensing arrangements with

third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates
or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when
needed, we may be required to delay, limit, reduce, or terminate our product development or future commercialization efforts or grant rights
to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Our limited operating history may make it difficult for you to evaluate the success of our business to date and to assess our future
viability.

We commenced active operations in late 2007, and our activities to date have been limited to, among other things, organizing and

staffing our company, business planning, raising capital, developing our product platform, identifying potential product candidates,
undertaking nonclinical studies, and conducting clinical trials. With the exception of oliceridine, our product candidates are in early stages
of development. We have not yet demonstrated our ability to obtain regulatory approvals, manufacture a product at commercial scale or
arrange for a third party to do so on our behalf, or conduct sales, marketing, and distribution activities necessary for successful product
commercialization. Consequently, any predictions you make about our future success or viability may not be as reliable as they could be if
we had a longer and more established operating history.

In addition, as a young business, we may encounter unforeseen expenses, difficulties, complications, delays, and other known and
unknown factors. We will need to significantly expand our capabilities to support future activities related to the approval, manufacture, and
commercialization of our product candidates. We may be unsuccessful in adding such capabilities.

We expect our financial condition and operating results to continue to fluctuate significantly from quarter to quarter and year to

year due to a variety of factors, many of which are beyond our control. Accordingly, you should not rely upon the results of any past
quarterly or annual periods as indications of future operating performance.

If we fail to satisfy all applicable Nasdaq continued listing requirements, including the $1.00 minimum closing bid price requirement,
our common stock may be delisted from Nasdaq, which could have an adverse impact on the liquidity and market price of our common
stock.

Our common stock is currently listed on the Nasdaq Global Select Market, or Nasdaq, which has qualitative and quantitative

continued listing requirements, including corporate governance requirements, public float requirements and the $1.00 minimum closing bid
price requirement. On December 18, 2018, we received a letter from the Listing Qualifications Department of Nasdaq indicating that, for
the 30 consecutive business days, the bid price for our common stock had closed below the minimum $1.00 per share required for continued
listing on Nasdaq under Nasdaq Listing Rule 5450(a)(1). While we regained compliance with this rule, in the future, if our common stock
trades at closing bid prices below $1.00 for 30 consecutive business days, or if we are unable to satisfy any of the other continued listing
requirement, Nasdaq may take steps to delist our common stock. A delisting of our common stock could adversely affect the market
liquidity of our common stock, decrease the market price of our common stock and adversely affect our ability to obtain financing for the
continuation of our operations.

Risks Related to Regulatory Approval of Our Product Candidates

If we are not able to obtain, or if there are delays in obtaining, required regulatory approvals, we will not be able to timely
commercialize, or to commercialize at all, our product candidates, and our ability to generate revenue will be materially impaired.

Our product candidates and the activities associated with their development and commercialization, including their design, testing,
manufacture, safety, efficacy, recordkeeping, labeling, storage, approval, advertising, promotion, sale and distribution, are subject to
comprehensive regulation by the FDA and other regulatory agencies in the United States and by the European Medicines Agency and
similar regulatory authorities outside the United States. Failure to obtain marketing approval for our product candidates will prevent us from
commercializing these product candidates and will significantly limit our ability to generate revenue in the future. To date, we have not
received approvals to market any of our product candidates from regulatory authorities in any jurisdiction, and in the United States have
received a CRL related to the NDA for oliceridine, and we may never be successful in obtaining any such approvals. In March 2019, based
on its review of data from the Company’s Phase 3 studies of oliceridine, the FDA informed us that under the conditions studied, these data
were not sufficient to support the continuation of FDA’s previously granted Breakthrough Therapy designation.

We have only limited experience in filing and supporting the applications necessary to gain marketing approvals, and we have
relied and expect to continue to rely on third parties to assist us in this process. Securing marketing approval requires the submission of
extensive nonclinical and clinical data and supporting information to regulatory authorities for each therapeutic indication to establish the
product candidate’s safety and efficacy. Securing marketing approval also requires the submission of information about the product
manufacturing process to, and inspection of manufacturing facilities by, the regulatory authorities. Our product candidates may not be
effective, may be only moderately effective, or may prove to have undesirable or unintended side effects, toxicities or other characteristics
that may preclude our obtaining marketing approval or prevent or limit commercial use. If any of our product candidates receives marketing
approval, the accompanying label may limit the approved use of our drug in this way, which could limit sales of the product. The process of
obtaining marketing approvals, both in the United States and abroad, is expensive, may take many years if approval is obtained at all, and
can vary substantially based upon a variety of factors, including the type, complexity, and novelty of the product candidates involved.
Changes in marketing approval policies during the development period, changes in or the enactment of additional statutes or regulations, or
changes in regulatory review for each submitted product application, may cause delays in the approval or rejection of an application.

Our MOR targeted product candidates, including oliceridine, may require Risk Evaluation and Mitigation Strategies, which could delay
the approval of these product candidates and increase the cost, burden and liability associated with the commercialization of these
product candidates.

Risk Evaluation and Mitigation Strategy, or REMS, are imposed by the FDA to assure safe use of the product candidates, either as

a condition of product candidate approval or on the basis of new safety information. Our MOR product candidates and our other product
candidates may require a REMS. The REMS may include medication guides for patients, special communication plans to healthcare
professionals or elements to assure safe use such as restricted distribution methods, patient registries and/or other risk minimization tools.
We cannot predict the specific REMS that may be required as part of the FDA’s approval of our product candidates. Any of these
limitations on approval or marketing could restrict the commercial promotion, distribution, prescription, or dispensing of our product
candidates, if approved. Depending on the extent of the REMS requirements, these requirements may significantly increase our costs to
commercialize these product candidates and could negatively affect sales. Furthermore, risks of our product candidates that are not
adequately addressed through proposed REMS for such product candidates also may prevent or delay their approval for commercialization.

33

 
 
Table of Contents

If approved by the FDA, our MOR targeted product candidates, including oliceridine, are likely to be classified as controlled substances,
and the making, use, sale, importation, exportation and distribution of controlled substances are subject to regulation by state, federal
and foreign law enforcement and other regulatory agencies.

Our MOR targeted product candidates, including oliceridine, are likely to be classified as controlled substances, which are subject

to state, federal and foreign laws and regulations regarding their manufacture, use, sale, importation, exportation and distribution. Controlled
substances are regulated under the Federal Controlled Substances Act of 1970, or CSA, and regulations of the DEA.

The DEA regulates controlled substances as Schedule I, II, III, IV or V substances. Schedule I substances by definition have no

established medicinal use and may not be marketed or sold in the United States. A pharmaceutical product may be listed as Schedule II, III,
IV or V, with Schedule II substances considered to present the highest risk of abuse and Schedule V substances the lowest relative risk of
abuse among such substances. If approved by the FDA, we expect oliceridine to be regulated by the DEA as a Schedule II controlled
substance.

Various states also independently regulate controlled substances. Though state-controlled substances laws often mirror federal law,

because the states are separate jurisdictions, they may separately schedule drugs as well. While some states automatically schedule a drug
when the DEA does so, in other states there must be rulemaking or a legislative action. State scheduling may delay commercial sale of any
controlled substance drug product for which we obtain federal regulatory approval and adverse scheduling could impair the commercial
attractiveness of such product. We or our collaborators must also obtain separate state registrations in order to be able to obtain, handle and
distribute controlled substances for clinical trials or commercial sale, and failure to meet applicable regulatory requirements could lead to
enforcement and sanctions from the states in addition to those from the DEA or otherwise arising under federal law.

For any of our product candidates classified as controlled substances, we and our suppliers, manufacturers, contractors, customers
and distributors are required to obtain and maintain applicable registrations from state, federal and foreign law enforcement and regulatory
agencies and comply with state, federal and foreign laws and regulations regarding the manufacture, use, sale, importation, exportation and
distribution of controlled substances. There is a risk that DEA regulations may limit the supply of the compounds used in clinical trials for
our product candidates, and, in the future, the ability to produce and distribute our products in the volume needed to both meet commercial
demand and build inventory to mitigate possible supply disruptions.

Regulations associated with controlled substances govern manufacturing, labeling, packaging, testing, dispensing, production and

procurement quotas, recordkeeping, reporting, handling, shipment and disposal. These regulations increase the personnel needs and the
expense associated with development and commercialization of product candidates including controlled substances. The DEA, and some
states, conduct periodic inspections of registered establishments that handle controlled substances. Failure to obtain and maintain required
registrations or comply with any applicable regulations could delay or preclude us from developing and commercializing our product
candidates containing controlled substances and subject us to enforcement action. The DEA may seek civil penalties, refuse to renew
necessary registrations or initiate proceedings to revoke those registrations. In some circumstances, violations could lead to criminal
proceedings. Because of their restrictive nature, these regulations could limit commercialization of any of our product candidates that are
classified as controlled substances.

Failure to obtain marketing approval in international jurisdictions would prevent our product candidates from being marketed abroad.

To market and sell our products in the European Union, Asia, and many other jurisdictions, we, our current collaborators in South

Korea and China for oliceridine, or any future third-party collaborators must obtain separate marketing approvals and comply with
numerous and varying regulatory requirements. The approval procedure varies among countries and can involve additional testing. The time
required to obtain approval may differ substantially from that required to obtain FDA approval. The regulatory approval process outside the
United States generally includes all of the risks associated with obtaining FDA approval. In addition, in many countries outside the United
States, it is required that the product be approved for reimbursement before the product can be approved for sale in that country. We or our

34

 
Table of Contents

collaborators may not obtain approvals from regulatory authorities outside the United States on a timely basis, if at all. Approval by the
FDA does not ensure approval by regulatory authorities in other countries or jurisdictions, and approval by one regulatory authority outside
the United States does not ensure approval by regulatory authorities in other countries or jurisdictions or by the FDA. However, the failure
to obtain approval in one jurisdiction, including if we are unable to obtain approval of oliceridine in the United States, may compromise our
ability to obtain approval elsewhere. We may not be able to file for marketing approvals and may not receive necessary approvals to
commercialize our products in any market.

Any product candidate for which we obtain marketing approval could be subject to post‑marketing restrictions or withdrawal from the
market and we may be subject to penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems
with our products, when and if any of them are approved.

Any product candidate for which we obtain marketing approval, along with the manufacturing processes, post‑approval clinical
data, labeling, advertising, and promotional activities for such product, will be subject to ongoing requirements of and review by the FDA
and other regulatory authorities. These requirements include submissions of safety and other post‑marketing information and reports,
registration, and listing requirements, current good manufacturing practice, or cGMP, requirements relating to manufacturing, quality
control, quality assurance and corresponding maintenance of records and documents, requirements regarding the distribution of samples to
physicians and recordkeeping. Even if marketing approval of a product candidate is granted, the approval may be subject to limitations on
the indicated uses for which the product may be marketed or to the conditions of approval, including the requirement to implement a REMS.
If any of our product candidates receives marketing approval, the accompanying label may limit the approved use of our drug, which could
limit sales of the product.

The FDA also may impose requirements for costly post‑marketing studies or clinical trials and surveillance to monitor the safety or

efficacy of the product. The FDA closely regulates the post‑approval marketing and promotion of drugs to ensure drugs are marketed only
for the approved indications and in accordance with the provisions of the approved labeling. However, companies may share truthful and
not misleading information that is otherwise consistent with a product’s FDA approved labeling. The FDA imposes stringent restrictions on
manufacturers’ communications regarding off‑label use and if we do not market our products for only their approved indications, we may
be subject to enforcement action for off‑label marketing. Violations of the Federal Food, Drug, and Cosmetic Act relating to the promotion
of prescription drugs may lead to investigations alleging violations of federal and state healthcare fraud and abuse laws, as well as state
consumer protection laws.

In addition, later discovery of previously unknown adverse events or other problems with our products, manufacturers or

manufacturing processes, or failure to comply with regulatory requirements, may yield various results, including:

·

·

·

·

·

·

·

·

the need to generate additional clinical data and provide information to the FDA to sufficiently address the items identified in the
CRL for oliceridine to allow for the future approval of oliceridine;

restrictions on such products, manufacturers or manufacturing processes;

restrictions on the labeling or marketing of a product;

restrictions on product distribution or use;

requirements to conduct post‑marketing studies or clinical trials;

warning letters;

withdrawal of the products from the market;

refusal to approve pending applications or supplements to approved applications that we submit;

·

recall of products;

fines, restitution or disgorgement of profits or revenue;

suspension or withdrawal of marketing approvals;

refusal to permit the import or export of our products;

product seizure; or

injunctions or the imposition of civil or criminal penalties.

The FDA’s policies may change and additional government regulations may be enacted that could prevent, limit or delay
regulatory approval of our product candidates. If we are slow or unable to adapt to changes in existing requirements or the adoption of new
requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have
obtained.

Risks Related to the Discovery and Development of Our Product Candidates

Our research and development efforts have been focused on discovering and developing novel drugs based on biased ligands, and the
approach we are taking to discover and develop drugs is not proven and may never lead to marketable products.

The development of drugs based on biased ligands is an emerging field, and the scientific discoveries that form the basis for our

historical efforts to discover and develop product candidates are relatively new. The scientific evidence to support the feasibility of
developing differentiated product candidates based on these discoveries is both preliminary and limited. We believe that we were the first
company to conduct a clinical trial of a product candidate based on the concept of biased ligands. Therefore, we do not know if our approach
will be successful or will ultimately lead to the approval of any current or future product candidate.

We are early in our development efforts and have only one product candidate, oliceridine, for which we have submitted an NDA to the
FDA. If we are unable to successfully complete development and commercialization of our product candidates, either on our own or
with a partner, or experience significant delays in doing so, our business will be materially harmed.

We are early in our development efforts and have only one product candidate, oliceridine, for which we have completed Phase 3
development, submitted an NDA to the FDA and have received a CRL. To this point, we have invested substantially all of our efforts and
financial resources in the identification and development of biased ligands. Our ability to generate product revenue, which we do not expect
will occur for the foreseeable future, if ever, will depend heavily on the successful development and eventual commercialization of our
product candidates. The success of our product candidates will depend on several factors, including the following:

·

·

·

successful completion of nonclinical studies and clinical trials;

receipt of marketing approvals from applicable regulatory authorities;

obtaining, maintaining, and protecting our intellectual property portfolio, including patents and trade secrets, and regulatory
exclusivity for our product candidates;

· making arrangements with third-party manufacturers for, or establishing, commercial manufacturing capabilities;

36

 
Table of Contents

·

·

·

·

launching commercial sales of the products, if and when approved, whether alone or in collaboration with others;

acceptance of our products, if and when approved, by patients, the medical community, and third-party payors;

effectively competing with other therapies;

obtaining and maintaining healthcare coverage of our products and adequate reimbursement; and

· maintaining a continued acceptable safety profile of our products following approval.

If we do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or an inability

to successfully commercialize our product candidates, which would materially harm our business.

We may not be successful in our efforts to expand our pipeline of product candidates.

One element of our strategy has been to expand our pipeline of therapeutics based on biased ligands and advance these product

candidates through clinical development for the treatment of a variety of indications. Until recently, we maintained an active discovery
research effort. In October 2017, we made the decision to halt our early stage research, although we continue to assess the future
development of a series of novel S1P modulators. Without internal discovery research capabilities, we will need to expand our pipeline
through other means, including, for example, by in-licensing product candidates for further development. We may not be able to identify,
acquire, and develop product candidates that are safe and effective. Even if we are successful in continuing to expand our pipeline, the
potential product candidates that we identify or in-license may not be suitable for clinical development, including as a result of being shown
to have harmful side effects or other characteristics that indicate that they are unlikely to receive marketing approval and achieve market
acceptance. If we do not successfully develop and commercialize product candidates, we will not be able to obtain product revenue in future
periods, which would make it unlikely that we would ever achieve profitability.

Nonclinical and clinical drug development involves a lengthy and expensive process, with an uncertain outcome. We may incur
additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our
product candidates.

Clinical testing is expensive, can take many years to complete, and has a high risk of failure. It is impossible to predict when or if

any of our product candidates will prove effective or safe in humans or will receive regulatory approval. Before obtaining marketing
approval from regulatory authorities for the sale of any product candidate, we must complete nonclinical studies and then conduct extensive
clinical trials to demonstrate the safety and efficacy of our product candidates in humans. A failure of one or more clinical trials can occur at
any stage of testing. The outcome of nonclinical testing and early clinical trials may not be predictive of the success of later clinical trials,
and interim results of a clinical trial do not necessarily predict final results. Moreover, nonclinical and clinical data often are susceptible to
varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in nonclinical
studies and clinical trials have nonetheless failed to obtain marketing approval of their products. We may experience numerous unforeseen
events during, or as a result of, clinical trials, which could delay or prevent our ability to receive marketing approval or subsequently to
commercialize our product candidates, including:

·

·

·

regulators or institutional review boards may not authorize us or our investigators to commence a clinical trial or conduct a
clinical trial at prospective trial sites;

we may experience delays in reaching, or fail to reach, agreement on acceptable clinical trial contracts or clinical trial protocols
with prospective trial sites;

clinical trials of our product candidates may produce negative or inconclusive results, and we may decide, or regulators may
require us, to conduct additional clinical trials or abandon product development programs;

37

 
Table of Contents

·

·

·

·

·

·

·

the number of patients required for clinical trials of our product candidates may be larger than we anticipate, enrollment in these
clinical trials may be slower than we anticipate, or participants may drop out of these clinical trials at a higher rate than we
anticipate;

our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely
manner, or at all;

we may have to suspend or terminate clinical trials of our product candidates for various reasons, including a finding that the
participants are being exposed to unacceptable health risks;

regulators or institutional review boards may require that we or our investigators suspend or terminate clinical research for
various reasons, including noncompliance with regulatory requirements or a finding that the participants are being exposed to
unacceptable health risks;

the cost of clinical trials of our product candidates may be greater than we anticipate;

the supply or quality of our product candidates or other materials necessary to conduct clinical trials of our product candidates
may be insufficient or inadequate; and

our product candidates may have undesirable side effects or other unexpected characteristics, causing us or our investigators,
regulators or institutional review boards to suspend or terminate the trials.

If we are required to conduct additional clinical trials or other testing of our product candidates beyond those that we currently

contemplate, if we are unable to successfully complete clinical trials of our product candidates or other testing, if the results of these trials or
tests are not positive or are only modestly positive or if there are safety concerns, we may:

·

·

·

·

·

·

be delayed in obtaining marketing approval for our product candidates;

not obtain marketing approval at all;

obtain approval for indications or patient populations that are not as broad as intended or desired;

obtain approval with labeling that includes significant use or distribution restrictions or safety warnings;

be subject to additional post‑marketing testing and/or reporting requirements; or

have the product removed from the market after obtaining marketing approval.

Our product development costs also will increase if we experience delays in testing or in receiving marketing approvals. We do not
know whether any of our nonclinical studies or clinical trials will begin as planned, will need to be restructured or will be completed on
schedule, or at all. Significant nonclinical study or clinical trial delays also could shorten any periods during which we may have the
exclusive right to commercialize our product candidates or allow our competitors to bring products to market before we do and impair our
ability to successfully commercialize our product candidates, thereby harming our business and results of operations.

If we experience delays or difficulties in the enrollment of patients in clinical trials, our receipt of necessary regulatory approvals could
be delayed or prevented.

We may not be able to initiate or continue clinical trials for our product candidates if we are unable to locate and enroll a sufficient

number of eligible patients to participate in these trials as required by the FDA or similar regulatory authorities outside the United States.
Some of our competitors have ongoing clinical trials for product candidates that treat the same indications as our product candidates, and
patients who would otherwise be eligible for our

38

 
Table of Contents

clinical trials may instead enroll in clinical trials of our competitors' product candidates. Patient enrollment is affected by other factors
including:

·

·

·

·

·

·

·

the severity of the disease under investigation;

the eligibility criteria for the study in question;

the perceived risks and benefits of the product candidate under study;

the efforts to facilitate timely enrollment in clinical trials;

the patient referral practices of physicians;

the ability to monitor patients adequately during and after treatment; and

the proximity and availability of clinical trial sites for prospective patients.

Our inability to enroll a sufficient number of patients for our clinical trials would result in significant delays and could require us to

abandon one or more clinical trials altogether. Enrollment delays in our clinical trials may result in increased development costs for our
product candidates, which would cause the value of our company to decline and limit our ability to obtain additional financing.

If serious adverse or unacceptable side effects are identified during the development of our product candidates, we may need to abandon
or limit our development of some of our product candidates.

If our product candidates are associated with adverse side effects in clinical trials or have characteristics that are unexpected, we

may need to abandon their development or limit development to more narrow uses or subpopulations in which the side effects or other
characteristics are less prevalent, less severe, or more acceptable from a risk-benefit perspective. In our industry, many compounds that
initially showed promise in early stage testing have later been found to cause side effects that prevented further development of the
compound or significantly limited its commercial opportunity.

Across the Phase 3 clinical development program for oliceridine, there were three suspected unexpected serious adverse reactions,
or SUSARs, reported to the FDA: one each for instances of post-operative ileus and lethargy, and one patient who experienced hepato-renal
failure. In addition, in the thorough QT study we conducted as part of the development of oliceridine, we observed no concentration-related
effects of oliceridine on QT, but we did observe a small QT prolongation, crossing the threshold of regulatory concern, at the
supratherapeutic dose. In our Phase 3 program, we included ECG monitoring to capture any potential delayed effects of oliceridine on the
QT interval. While the data we collected in these studies did not show any oliceridine-specific effects on QT and there were not any clinical
sequelae associated with a prolonged QT interval, the FDA indicated in the oliceridine CRL that they would like to see additional clinical
data related to the QT interval. If we ultimately conduct an additional study to gather this data, we cannot assure you that the results of such
study will not show any oliceridine-specific effects on the QT interval, that there will not be any clinical sequelae associated with any
prolonged QT interval, or that the study itself and the results obtained will address the FDA’s concerns sufficiently to allow for the future
approval of oliceridine.

If our clinical trials reveal a high and unacceptable severity and prevalence of side effects, these trials could be suspended or

terminated, and the FDA or comparable foreign regulatory authorities could order us to cease further development or deny approval of our
product candidates for any or all targeted indications. Drug-related side effects could affect patient recruitment or the ability of enrolled
patients to complete the trial and could result in potential product liability claims.

39

 
Table of Contents

Additionally, if one or more of our product candidates receives marketing approval, and we or others later identify undesirable side

effects caused by such products, a number of potentially significant negative consequences could result, including:

·

·

·

·

regulatory authorities may require additional warnings on the label or even withdraw approvals of such product;

we may be required to create a medication guide outlining the risks of such side effects for distribution to patients, if one is not
required in connection with regulatory approval;

we could be sued and held liable for harm caused to patients; and

our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of the particular product candidate, if

approved.

Oliceridine and TRV734 are both biased ligands targeted at the MOR. Common adverse reactions for agonists of the MOR include

respiratory depression, constipation, nausea, vomiting, and addiction. In rare cases, MOR agonists can cause respiratory arrest requiring
immediate medical intervention. Since oliceridine and TRV734 also modulate the MOR, these adverse reactions and risks likely will apply
to the use of oliceridine and TRV734. One healthy subject in the 0.25 mg dosing cohort of our Phase 1 clinical trial of oliceridine
experienced a severe episode of vasovagal syncope during which he fainted and his pulse stopped. These were considered severe adverse
events. It is possible that serious adverse vasovagal events could occur in other patients dosed with oliceridine. Agonists at the DOR have
been associated with a risk of seizures. TRV250, our DOR product candidate, targets the same receptor as other programs that have been
associated with seizures and, accordingly, it is possible that TRV250 will be associated with similar side effects. In such case, we likely
would discontinue further development of TRV250 for the treatment of migraines.

We may expend our limited resources to pursue a particular product candidate or indication and thereby fail to capitalize on other
product candidates or indications that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and managerial resources, we focus on research programs and product candidates that we
identify for specific indications. As a result, we may forego or delay pursuit of opportunities with other product candidates or for other
indications that later prove to have fewer clinical or regulatory risks and/or greater commercial potential. Our resource allocation decisions
may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future
research and development programs and product candidates for specific indications may not yield any commercially viable products. If we
do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to
that product candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been more
advantageous for us to retain sole development and commercialization rights to such product candidate.

Risks Related to the Commercialization of Our Product Candidates

Even if any of our product candidates receives marketing approval, it may fail to achieve the degree of market acceptance by physicians,
patients, third-party payors, and others in the medical community necessary for commercial success.

If any of our product candidates receives marketing approval, it may nonetheless fail to gain sufficient market acceptance by

physicians, patients, third-party payors, and others in the medical community. If our product candidates do not achieve an adequate level of
acceptance, we may not generate significant product revenue and we may not attain

40

 
Table of Contents

profitability. The degree of market acceptance of our product candidates, if approved for commercial sale, will depend on a number of
factors, including:

·

·

·

·

·

·

·

·

·

·

the efficacy, safety and potential advantages compared to alternative treatments;

the timing of market introduction of the product candidate as well as competitive products;

our ability to offer the product for sale profitably and at competitive prices;

the convenience and ease of administration compared to alternative treatments;

the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;

the strength of sales, marketing, and distribution support;

the availability of third-party payor coverage and adequate reimbursement;

the prevalence and severity of any side effects;

the clinical indications for which the product is approved; and

any restrictions on the use of our products, both on their own and together with other medications.

If we are unable to establish manufacturing, sales, marketing, and distribution capabilities or to enter into agreements with third parties
to produce, market, sell, and distribute our product candidates, we may not be successful in commercializing our product candidates if
and when they are approved.

We currently have limited resources directed toward the manufacturing, marketing, sales, and distribution of pharmaceutical

products and have limited experience and capabilities in this area. To commercialize any product candidates that receive marketing
approval, we would need to build manufacturing, marketing, sales, distribution, managerial and other non-technical capabilities or make
arrangements with third parties to perform these services, and we may not be successful in doing so. If we successfully develop and obtain
regulatory approval for any of our product candidates, we expect to build or outsource a targeted specialist sales force to market or co-
promote the product in the United States; we currently do not expect to build sales, manufacturing and distribution capabilities outside of the
United States, although this expectation could change in the future. There are substantial risks involved with establishing sales, marketing,
and distribution capabilities. For example, recruiting and training a sales force is expensive and time consuming and could delay any
product launch. If the commercial launch of a product candidate is delayed or does not occur for any reason, we would have prematurely or
unnecessarily incurred certain commercialization expenses. This may be costly, and our investment would be lost if we cannot retain or
reposition our sales and marketing personnel.

There are a number of factors that may inhibit our efforts to commercialize our products on our own, including:

our inability to recruit, train and retain adequate numbers of effective sales and marketing personnel or to outsource these tasks to
a third party;

the inability of sales personnel to obtain access to physicians or other relevant personnel or educate adequate numbers of
physicians or others on the benefit of our product candidates;

the lack of complementary or other products to be offered by sales personnel, which may put us at a competitive disadvantage
from the perspective of sales efficiency relative to companies with more extensive product lines; and

·

·

·

41

 
Table of Contents

·

unforeseen costs and expenses associated with creating a sales and marketing organization.

As an alternative to establishing our own sales force, we may choose to partner with third parties that have well-established direct

sales forces to sell, market and distribute our products, particularly in markets outside of the United States. If we are unable to enter into
collaborations with third parties for the commercialization of approved products, if any, on acceptable terms or at all, or if any such partner
does not devote sufficient resources to the commercialization of our product or otherwise fails in commercialization efforts, we may not be
able to successfully commercialize any of our product candidates that receive regulatory approval.

For oliceridine, we will need to partner with one or more third parties to sell, market and distribute this product, if approved,

outside the United States. In April 2018 and May 2018, we entered into exclusive licensing agreements for the development and
commercialization of oliceridine in South Korea and China, respectively. Such partnerships in South Korea and China may not be
successful, and we may be unsuccessful in our efforts to secure additional partnerships outside the United States.

We face substantial competition, which may result in others discovering, developing, or commercializing products before or more
successfully than we do.

The development and commercialization of new drug products is highly competitive. We face competition with respect to our

current product candidates, and will face competition with respect to any product candidates that we may seek to develop or commercialize
in the future, from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide. In
addition to existing therapeutic treatments for the indications we are targeting with our product candidates, if any of our product candidates
achieves regulatory approval, we also face potential competition from other drug candidates in development by other companies. If
approved, oliceridine also may compete against, or be used in combination with, OFIRMEV® (IV acetaminophen), marketed by
Mallinckrodt plc, with EXPAREL® (liposomal bupivacaine), marketed by Pacira Pharmaceuticals, Inc., CALDOLOR® (IV ibuprofen),
marketed by Cumberland Pharmaceuticals, and DSUVIA™ (sublingual sufentanil nanotabs), marketed by AcelRx. In addition to currently
marketed IV analgesics, we are aware of a number of products in development that are aimed at improving the treatment of moderate-to-
severe acute pain. AcelRx Pharmaceuticals, Inc. is developing ZALVISO™, a patient controlled analgesia device which dispenses
sublingual sufantanil nanotabs. Innocoll Holdings plc, and Heron Therapeutics Inc. have proprietary long‑acting reformulations of
bupivacaine in development. Recro Pharma, Inc. is developing an IV version of the NSAID meloxicam. Cara Therapeutics Inc. is
developing IV and oral dose forms of a peripherally restricted κ‑opioid receptor agonist, which has been administered in combination with
mu‑opioids in clinical trials. Avenue Therapeutics, Inc. is developing an IV version of the generic opioid tramadol for moderate-to-severe
acute pain. Some of these potential competitive compounds are being developed by large, well-financed, and experienced pharmaceutical
and biotechnology companies, or have been partnered with such companies, which may give them development, regulatory and marketing
advantages over us.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer,

more effective, have fewer or less severe side effects, are more convenient or are less expensive than any products that we may develop.
Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours,
which could result in our competitors establishing a strong market position before we are able to enter the market. In addition, our ability to
compete may be affected in many cases by insurers or other third-party payors seeking to encourage the use of generic products. Generic
products are currently on the market for the indications that we are pursuing. If our product candidates achieve marketing approval, we
expect that they will be priced at a significant premium over competing generic products.

Some of the companies against which we are competing or against which we may compete in the future have significantly greater

financial resources and expertise than we do in research and development, manufacturing, nonclinical testing, conducting clinical trials,
obtaining regulatory approvals, and selling and marketing approved products. Mergers and acquisitions in the pharmaceutical and
biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller and
other early stage companies also may prove to be significant competitors, particularly through collaborative arrangements with large and
established companies. These third parties compete with us in recruiting and retaining qualified scientific and management

42

 
Table of Contents

personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or
necessary for, our programs.

Even if we or any future collaborators are able to commercialize any of our product candidates, the product candidates may become
subject to unfavorable pricing regulations, third-party payor coverage and reimbursement policies, healthcare reform initiatives, or
regulatory or political concerns.

Both our and our collaborators’ ability to commercialize any of our product candidates successfully will depend, in part, on the
extent to which coverage and adequate reimbursement for these products and related treatments will be available from government payor
programs at the federal and state level, including Medicare and Medicaid, private health insurers, managed care plans and other
organizations. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide
which medications they will pay for and establish reimbursement levels. In addition, for hospital products, a private health insurer or
Medicare will typically reimburse a fixed fee for certain procedures, including in‑patient surgeries. Pharmaceutical products such as
oliceridine, if approved, that may be used in connection with the surgery generally will not be separately reimbursed and, therefore, a
hospital would have to assess the cost of oliceridine, if approved, relative to its benefits. Current or future efforts to limit the level of
reimbursement for in‑patient hospital procedures could cause a hospital to decide not to use oliceridine, if approved by the FDA. A primary
trend in the U.S. healthcare industry and elsewhere is cost containment. Government authorities and third-party payors have attempted to
control costs by limiting coverage and the amount of reimbursement for particular medications or procedures. Increasingly, third-party
payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged
for medical products. Coverage and reimbursement may not be available for any drug that we or our collaborators commercialize and, even
if these are available, the level of reimbursement for a product or procedure may not be satisfactory. Inadequate reimbursement levels may
adversely affect the demand for, or the price of, any product candidate for which we or our collaborators obtain marketing approval.
Obtaining and maintaining adequate reimbursement for our products may be difficult. We may be required to conduct expensive
pharmacoeconomic studies to seek to justify coverage and reimbursement or the level of reimbursement relative to other therapies. If
coverage and adequate reimbursement are not available or reimbursement is available only to limited levels, we or our collaborators may not
be able to successfully commercialize any product candidates for which marketing approval is obtained.

There may be significant delays in obtaining coverage and reimbursement for newly approved drugs, and coverage may be more

limited than the indications for which the drug is approved by the FDA or analogous regulatory authorities outside the United States.
Moreover, eligibility for coverage and reimbursement does not imply that a drug will be paid for in all cases or at a rate that covers our
costs, including research, development, manufacture, sale, and distribution expenses. Interim reimbursement levels for new drugs, if
applicable, also may not be sufficient to cover our costs and may not be made permanent. Reimbursement rates may vary according to the
use of the drug and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost drugs and may
be incorporated into existing payments for other services. Net prices for drugs may be reduced by mandatory discounts or rebates required
by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from
countries where they may be sold at lower prices than in the United States. Third-party payors often rely upon Medicare coverage policy
and payment limitations in setting their own reimbursement policies. Our or our collaborators’ inability to promptly obtain coverage and
adequate reimbursement rates from both government‑funded and private payors for any approved drugs that we develop could adversely
affect our operating results, our ability to raise capital needed to commercialize drugs and our overall financial condition.

The regulations that govern marketing approvals, pricing, coverage and reimbursement for new drugs vary widely from country to

country. Current and future legislation may significantly change the approval requirements in ways that could involve additional costs and
cause delays in obtaining approvals. Some countries require approval of the sale price of a drug before it can be marketed. In many
countries, the pricing review period begins after marketing or licensing approval is granted. In some foreign markets, prescription
pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we or our
collaborators might obtain marketing approval for a drug in a particular country, but then be subject to price regulations that delay
commercial launch of the drug, possibly for lengthy time periods, and negatively impact our ability to generate revenue from the sale

43

 
Table of Contents

of the drug in that country. Adverse pricing limitations may hinder our ability to recoup our investment in one or more product candidates,
even if our product candidates obtain marketing approval.

In addition to the above factors, the approval and commercialization of oliceridine may be negatively impacted by changing
perceptions in the United States and elsewhere among regulators, legislators, and the general public concerning the approval, use, and abuse
of prescription opioid products. In the future, the FDA and other regulatory and legislative bodies may enact regulations that seek to limit
opioid prescribing and use. In response to these efforts and changing perceptions, physicians may determine to reduce the volume of opioid
prescriptions they prescribe to patients. Any of these changes could negatively impact both the timing and likelihood of FDA approval of
oliceridine, as well as the commercial opportunity, if approved.

There can be no assurance that our product candidates, if they are approved for sale in the United States or in other countries, will
be considered medically reasonable and necessary for a specific indication, that they will be considered cost‑effective by third-party payors,
that coverage or an adequate level of reimbursement will be available, or that third-party payors’ reimbursement policies will not adversely
affect our ability to profitably sell our product candidates if they are approved for sale.

Product liability lawsuits against us could cause us to incur substantial liabilities and limit commercialization of any products that we
may develop.

We face an inherent risk of product liability exposure related to the testing of our product candidates in human clinical trials and
will face an even greater risk if we commercially sell any products that we may develop. For example, we may be sued if any product we
develop allegedly causes injury or is found to be otherwise unsuitable during clinical testing, manufacturing, marketing or sale. Any such
product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the
product, negligence, strict liability or a breach of warranties. If we cannot successfully defend ourselves against claims that our product
candidates or products caused injuries, we will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may
result in:

·

·

·

·

·

·

·

·

·

·

decreased demand for any product candidates or products that we may develop;

injury to our reputation and significant negative media attention;

withdrawal of clinical trial participants;

initiation of investigations by regulators;

significant costs to defend the related litigation;

product recalls, withdrawals or labeling, marketing or promotional restrictions;

substantial monetary awards to trial participants or patients;

loss of revenue;

reduced resources of our management to pursue our business strategy; and

the inability to commercialize any products that we may develop.

We currently maintain product liability insurance coverage at levels that may be inadequate to cover all liabilities we may incur.

We will likely need to increase our insurance coverage as we expand our clinical trials or if we commence commercialization of our product
candidates. Insurance coverage is increasingly expensive, and in the future

44

 
Table of Contents

may be difficult to obtain for products such as oliceridine. We may not be able to maintain insurance coverage at a reasonable cost or in an
amount adequate to satisfy any liability that may arise.

Risks Related to Our Dependence on Third Parties

Our current collaborators are, and any future relationships or collaborations we may enter into may be, important to us. If we are
unable to maintain our relationship with any of these collaborations, or if our relationship with these collaborators is not successful, our
business could be adversely affected.

We have limited capabilities for product development, sales, marketing, and distribution. For our product candidates, we may in

the future determine to collaborate with pharmaceutical and biotechnology companies for the development and potential commercialization
of these candidates. For oliceridine, we entered into license agreements with partners in South Korea and China in 2018 whereby these
parties will develop, seek regulatory approval for, and, if successful, commercialize oliceridine. We face significant competition in seeking
appropriate collaborators. Our ability to reach a definitive agreement for collaboration will depend, among other things, upon our assessment
of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration, and the proposed collaborator’s
evaluation of a number of factors. If we are unable to reach agreements with suitable collaborators on a timely basis, on acceptable terms, or
at all, we may have to curtail the development of a product candidate, reduce or delay its development program or one or more of our other
development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our
expenditures and undertake development or commercialization activities at our own expense. If we elect to fund and undertake development
or commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to
us on acceptable terms or at all. If we fail to enter into collaborations and do not have sufficient funds or expertise to undertake the necessary
development and commercialization activities, we may not be able to further develop our product candidates or bring them to market or
continue to develop our product platform and our business may be materially and adversely affected.

·

·

·

·

·

·

·

Any future collaborations we might enter into with third parties, may pose a number of risks, including the following:

collaborators have significant discretion in determining the efforts and resources that they will apply to these collaborations;

collaborators may not perform their obligations as expected;

collaborators may elect not to continue development or commercialization programs or may not pursue commercialization of any
product candidates that achieve regulatory approval based on clinical trial results, changes in the collaborators’ strategic focus or
available funding, or external factors, such as an acquisition, that divert resources or create competing priorities;

collaborators may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or abandon a
product candidate, repeat or conduct new clinical trials, or require a new formulation of a product candidate for clinical testing;

collaborators could fail to make timely regulatory submissions for a product candidate;

collaborators may not comply with all applicable regulatory requirements or may fail to report safety data in accordance with all
applicable regulatory requirements;

collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with our
products or product candidates if the collaborators believe that competitive products are more likely to be successfully developed
or can be commercialized under terms that are more economically attractive than ours;

45

 
Table of Contents

·

·

product candidates discovered in collaboration with us may be viewed by our collaborators as competitive with their own product
candidates or products, which may cause collaborators to limit or eliminate efforts and resources to the commercialization of our
product candidates;

a collaborator with marketing and distribution rights to one or more of our product candidates that achieve regulatory approval
may not commit sufficient resources to the marketing and distribution of such product or products;

disagreements with collaborators, including disagreements over proprietary rights, contract interpretation, or the preferred course
of development, might cause delays or termination of the research, development or commercialization of product candidates,
might lead to additional responsibilities for us with respect to product candidates, or might result in litigation or arbitration, any of
which would be time-consuming and expensive;

collaborators may not properly maintain or defend our intellectual property rights or may use our proprietary information in such
a way as to invite litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to
potential litigation;

collaborators may infringe the intellectual property rights of third parties, which may expose us to litigation and potential liability;
and

collaborations may be terminated at the convenience of the collaborator and, if terminated, we could be required to raise
additional capital to pursue further development or commercialization of the applicable product candidates.

If any collaborations we might enter into in the future do not result in the successful development and commercialization of

products or if one of our collaborators terminates its agreement with us, we may not receive any future research funding or milestone or
royalty payments under the collaboration. If we do not receive the funding we expect under these agreements, our development of our
product platform and product candidates could be delayed and we may need additional resources to develop our product candidates and our
product platform. The risks relating to our product development, regulatory approval and commercialization described in this Annual
Report also apply to the activities of our therapeutic program collaborators.

If a future collaborator of ours is involved in a business combination, the collaborator might deemphasize or terminate

development or commercialization of any product candidate licensed to it by us. If one of our collaborators terminates its agreement with us,
we may find it more difficult to attract new collaborators and our reputation in the business and financial communities could be adversely
affected.

We rely, and expect to continue to rely, on third parties to conduct our preclinical studies and clinical trials, and those third parties may
not perform satisfactorily, including failing to meet deadlines for the completion of such trials or complying with applicable regulatory
requirements.

We rely on third parties, such as contract research organizations, clinical research organizations, clinical data management
organizations, medical institutions, and clinical investigators to conduct our nonclinical studies and clinical trials for our product candidates.
The agreements with these third parties might terminate for a variety of reasons, including a failure to perform by the third parties. If we
need to enter into alternative arrangements, that could delay our product development activities.

Our reliance on these third parties for research and development activities will reduce our control over these activities but will not
relieve us of our responsibilities. For example, we will remain responsible for ensuring that each of our nonclinical studies and clinical trials
are conducted in accordance with the general investigational plan and protocols for the trial and for ensuring that our nonclinical studies are
conducted in accordance with good laboratory practice, or GLP, as appropriate. Moreover, the FDA requires us to comply with standards,
commonly referred to as good clinical practices, or GCPs, for conducting, recording and reporting the results of clinical trials to assure that
data and reported

46

 
Table of Contents

results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. Regulatory authorities
enforce these requirements through periodic inspections of trial sponsors, clinical investigators, and trial sites. If we or any of our clinical
research organizations fail to comply with applicable GCPs, the clinical data generated in our clinical trials may be deemed unreliable and
the FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing
applications. We cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any of
our clinical trials complies with GCP regulations. In addition, our clinical trials must be conducted with product produced under cGMP
regulations. Our failure to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval
process. We also are required to register ongoing clinical trials and post the results of completed clinical trials on a government sponsored
database, ClinicalTrials.gov, within specified timeframes. Failure to do so can result in fines, adverse publicity and civil and criminal
sanctions.

The third parties with whom we have contracted to help perform our nonclinical studies or clinical trials also may have
relationships with other entities, some of which may be our competitors. If these third parties do not successfully carry out their contractual
duties, meet expected deadlines, or conduct our nonclinical studies or clinical trials in accordance with regulatory requirements or our stated
protocols, we will not be able to obtain, or may be delayed in obtaining, marketing approvals for our product candidates and will not be able
to, or may be delayed in our efforts to, successfully commercialize our product candidates.

If any of our relationships with these third-party contract research organizations or clinical research organizations terminate, we

may not be able to enter into arrangements with alternative contract research organizations or clinical research organizations or to do so on
commercially reasonable terms. Switching or adding additional contract research organizations or clinical research organizations involves
additional cost and requires management time and focus. In addition, there is a natural transition period when a new contract research
organization or clinical research organization commences work. As a result, delays could occur that could compromise our ability to meet
our desired development timelines. Although we seek to carefully manage our relationships with our contract research organizations and
clinical research organizations, there can be no assurance that we will not encounter similar challenges or delays in the future.

We contract with third parties for the manufacture of our product candidates for nonclinical and clinical testing and expect to continue
to do so for commercialization. This reliance on third parties increases the risk that we will not have sufficient quantities of our product
candidates or products or such quantities at an acceptable cost, which could delay, prevent or impair our development or
commercialization efforts.

We have no internal manufacturing capabilities and do not have any manufacturing facilities. We rely, and expect to continue to

rely, on third parties for the manufacture of our product candidates for nonclinical and clinical testing, as well as for commercial
manufacture, if any of our product candidates receive marketing approval. This reliance on third parties increases the risk that we will not
have sufficient quantities of our product candidates or products or such quantities at an acceptable cost or quality, which could delay,
prevent or impair our development or commercialization efforts.

We also expect to rely on third-party manufacturers or third-party collaborators for the manufacture of commercial supply of any
product candidates for which our collaborators or we obtain marketing approval. We may be unable to establish any agreements with third-
party manufacturers or to do so on acceptable terms. Even if we are able to establish agreements with third-party manufacturers, reliance on
third-party manufacturers entails additional risks, including:

·

·

reliance on the third party for regulatory compliance and quality assurance;

the possible breach of the manufacturing agreement by the third party;

· manufacturing delays if our third-party manufacturers give greater priority to the supply of other products over our product

candidates or otherwise do not satisfactorily perform according to the terms of the agreement between us;

47

 
Table of Contents

·

·

the possible misappropriation of our proprietary information, including our trade secrets and know-how; and

the possible termination or nonrenewal of the agreement by the third party at a time that is costly or inconvenient for us.

The facilities used by our contract manufacturers to manufacture our product candidates and, potentially in the future, our products

must be approved by the FDA pursuant to inspections that will be conducted after we submit an NDA to the FDA. We do not control the
manufacturing process of, and are completely dependent on, our contract manufacturers for compliance with current cGMP regulations for
manufacture of our product candidates. Third-party manufacturers may not be able to comply with the cGMP regulations or similar
regulatory requirements outside the United States. Our failure, or the failure of our third-party manufacturers, to comply with applicable
regulations could result in sanctions being imposed on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension or
withdrawal of approvals, license revocation, seizures or recalls of product candidates or products, operating restrictions and criminal
prosecutions, any of which could significantly and adversely affect supplies of our products.

Our product candidates and any products that we may commercialize likely will compete with other product candidates and

products for access to manufacturing facilities. There are a limited number of manufacturers that operate under cGMP regulations and that
might be capable of manufacturing for us. Any performance failure on the part of our existing or future manufacturers could delay clinical
development or marketing approval. We do not currently have arrangements in place for redundant supply or a second source for bulk drug
substance. If our current contract manufacturers cannot perform as agreed, we may be required to replace such manufacturers. We may
incur added costs and delays in identifying and qualifying any replacement manufacturers.

The DEA restricts the importation of a controlled substance finished drug product when the same substance is commercially

available in the United States, which could reduce the number of potential alternative manufacturers for our MOR targeted product
candidates, including oliceridine. In addition, a DEA quota system controls and limits the availability and production of controlled
substances and the DEA also has authority to grant or deny requests for quota of controlled substances, which will likely include the active
ingredients in oliceridine. Supply disruptions could result from delays in obtaining DEA approvals for controlled substances or from the
receipt of quota of controlled substances that are insufficient to meet future product demand. The quota system also may limit our ability to
build inventory as a method for mitigating possible supply disruptions if oliceridine is approved for sale in the United States.

Our current and anticipated future dependence upon others for the manufacture of our product candidates or products may

adversely affect our future profit margins and our ability to commercialize any products that receive marketing approval on a timely and
competitive basis.

We also expect to rely on other third parties to store and distribute drug supplies for our clinical trials. Any performance failure on

the part of our distributors could delay clinical development or marketing approval of our product candidates or commercialization of our
products, producing additional losses and depriving us of potential product revenue.

We rely on clinical data and results obtained by third parties that could ultimately prove to be inaccurate or unreliable.

As part of our strategy to mitigate development risk, we seek to develop product candidates with validated mechanisms of action

and we utilize biomarkers to assess potential clinical efficacy early in the development process. This strategy necessarily relies upon clinical
data and other results obtained by third parties that may ultimately prove to be inaccurate or unreliable. Further, such clinical data and
results may be based on products or product candidates that are significantly different from our product candidates. If the third party data
and results we rely upon prove to be inaccurate, unreliable or not applicable to our product candidates, we could make inaccurate
assumptions and conclusions about our product candidates and our research and development efforts could be compromised.

Risks Related to Our Intellectual Property

If we are unable to obtain and maintain patent protection for our technology and products or if the scope of the patent protection
obtained is not sufficiently broad, our competitors could develop and commercialize technology and products similar or identical to ours,
and our ability to successfully commercialize our technology and products may be impaired.

Our success depends in large part on our ability to obtain and maintain patent protection in the United States and other countries

with respect to our product candidates. We seek to protect our proprietary position by filing patent applications in the United States and
abroad related to our product candidates.

The patent prosecution process is expensive and time-consuming, and we may not be able to file and prosecute all necessary or

desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we will fail to identify patentable aspects of
our research and development output before it is too late to obtain patent protection. Should we enter into collaborations with third parties,
we may be required to consult with or cede control to collaborators regarding the prosecution, maintenance and enforcement of our patents.
Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business.

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and

factual questions and has in recent years been the subject of much litigation. In addition, the laws of foreign countries may not protect our
rights to the same extent as the laws of the United States. For example, European patent law restricts the patentability of methods of
treatment of the human body more than United States law does. Publications of discoveries in the scientific literature often lag behind the
actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after a first
filing, or in some cases at all. Therefore, we cannot know with certainty whether we were the first to make the inventions claimed in our
owned or licensed patents or pending patent applications, or that we were the first to file for patent protection of such inventions. As a result,
the issuance, scope, validity, enforceability and commercial value of our patent rights are highly uncertain. Our pending and future patent
applications may not result in patents being issued which protect our technology or products, in whole or in part, or which effectively
prevent others from commercializing competitive technologies and products. Changes in either the patent laws or interpretation of the patent
laws in the United States and other countries may diminish the value of our patents or narrow the scope of our patent protection.

The Leahy-Smith America Invents Act, or the Leahy-Smith Act, could increase the uncertainties and costs surrounding the

prosecution of our patent applications and the enforcement or defense of our issued patents. On September 16, 2011, the Leahy-Smith Act
was signed into law. The Leahy-Smith Act includes a number of significant changes to United States patent law. These include provisions
that affect the way patent applications are prosecuted and may also affect patent litigation. The United States Patent and Trademark Office
continues to develop and implement new regulations and procedures to govern administration of the Leahy-Smith Act, and many of the
substantive changes to patent law associated with the Leahy-Smith Act, and in particular, the first to file provisions, only became effective
on March 16, 2013. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on the operation of our business.
However, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent
applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect on our business and
financial condition.

Moreover, we may be subject to a third-party preissuance submission of prior art to the United States Patent and Trademark

Office, or become involved in opposition, derivation, reexamination, inter partes review, post-grant review or interference proceedings
challenging our patent rights or the patent rights of others. An adverse determination in any such submission, proceeding or litigation could
reduce the scope of, render unenforceable, or invalidate, our patent rights, allow third parties to commercialize our technology or products
and compete directly with us, without payment to us, or result in our inability to manufacture or commercialize products without infringing
third-party patent rights. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, it
could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates.

49

 
Table of Contents

Even if our patent applications issue as patents, they may not issue in a form that will provide us with any meaningful protection,

prevent competitors from competing with us, or otherwise provide us with any competitive advantage. Our competitors may be able to
circumvent our owned or licensed patents by developing similar or alternative technologies or products in a non-infringing manner.

The issuance of a patent does not foreclose challenges to its inventorship, scope, validity or enforceability. Therefore, our owned

and licensed patents may be challenged in the courts or patent offices in the United States and abroad. Such challenges may result in loss of
exclusivity or freedom to operate or in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could
limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent
protection of our technology and products. Given the amount of time required for the development, testing and regulatory review of new
product candidates, patents protecting such product candidates might expire before or shortly after such product candidates are
commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from
commercializing products similar or identical to ours.

We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time
consuming, and unsuccessful.

Competitors may infringe our issued patents or other intellectual property. To counter infringement or unauthorized use, we may

be required to file infringement claims, which can be expensive and time consuming. Any claims we assert against perceived infringers
could provoke these parties to assert counterclaims against us alleging that we infringe their patents. In addition, in a patent infringement
proceeding, a court may decide that a patent of ours is invalid or unenforceable, in whole or in part, construe the patent’s claims narrowly or
refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An
adverse result in any litigation proceeding could put one or more of our patents at risk of being invalidated, rendered unenforceable, or
interpreted narrowly.

We may need to license certain intellectual property from third parties, and such licenses may not be available or may not be available
on commercially reasonable terms.

A third party may hold intellectual property, including patent rights that are important or necessary to the development of our

products. It may be necessary for us to use the patented or proprietary technology of third parties to commercialize our products, in which
case we would be required to obtain a license from these third parties on commercially reasonable terms, or our business could be harmed,
possibly materially.

Third parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which
would be uncertain and could have a material adverse effect on the success of our business.

Our commercial success depends upon our ability, and the ability of our collaborators, to develop, manufacture, market and sell

our product candidates and use our proprietary technologies without infringing the proprietary rights of third parties. There is considerable
intellectual property litigation in the biotechnology and pharmaceutical industries. We may become party to, or threatened with, future
adversarial proceedings or litigation regarding intellectual property rights with respect to our products and technology, including
interference or derivation proceedings before the United States Patent and Trademark Office. Third parties may assert infringement claims
against us based on existing patents or patents that may be granted in the future.

If we are found to infringe a third party’s intellectual property rights, we could be required to obtain a license from such third party

to continue developing and marketing our products and technology. However, we may not be able to obtain any required license on
commercially reasonable terms or at all. Even if we were able to obtain a license, it could be non‑exclusive, thereby giving our competitors
access to the same technologies licensed to us. We could be forced, including by court order, to cease commercializing the infringing
technology or product. In addition, we could be found liable for monetary damages, including treble damages and attorneys’ fees if we are
found to have willfully infringed a patent. A finding of infringement could prevent us from commercializing our product candidates or force
us to cease some of our business operations, which could materially harm our business. Claims that we have

50

 
Table of Contents

misappropriated the confidential information or trade secrets of third parties could have a similar negative impact on our business.

If we fail to comply with our obligations in our intellectual property licenses and funding arrangements with third parties, we could lose
rights that are important to our business.

We are currently party to license agreements for technologies that we use in conducting our drug discovery activities. In the future,

we may become party to licenses that are important for product development and commercialization. If we fail to comply with our
obligations under current or future license and funding agreements, our counterparties may have the right to terminate these agreements, in
which event we might not be able to develop, manufacture or market any product or utilize any technology that is covered by these
agreements or may face other penalties under the agreements. Such an occurrence could materially and adversely affect the value of a
product candidate being developed under any such agreement or could restrict our drug discovery activities. Termination of these
agreements or reduction or elimination of our rights under these agreements may result in our having to negotiate new or reinstated
agreements with less favorable terms, or cause us to lose our rights under these agreements, including our rights to important intellectual
property or technology.

We may be subject to claims by third parties asserting that our employees or we have misappropriated their intellectual property, or
claiming ownership of what we regard as our own intellectual property.

Many of our employees were previously employed at universities or other biotechnology or pharmaceutical companies, including

our competitors or potential competitors. Although we try to ensure that our employees do not use the proprietary information or know‑how
of others in their work for us, we may be subject to claims that these employees or we have used or disclosed intellectual property, including
trade secrets or other proprietary information, of any such employee’s former employer. Litigation may be necessary to defend against
these claims.

In addition, while it is our policy to require our employees and contractors who may be involved in the development of intellectual
property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each
party who in fact develops intellectual property that we regard as our own. Our and their assignment agreements may not be self‑executing
or may be breached, and we may be forced to bring claims against third parties, or defend claims they may bring against us, to determine
the ownership of what we regard as our intellectual property.

If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual
property rights or personnel. Even if we are successful in prosecuting or defending against such claims, litigation could result in substantial
costs and be a distraction to management.

Intellectual property litigation could cause us to spend substantial resources and distract our personnel from their normal
responsibilities.

Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur

significant expenses and could distract our technical and management personnel from their normal responsibilities. In addition, there could
be public announcements of the results of hearings, motions or other interim proceedings or developments and if securities analysts or
investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock. Such litigation or
proceedings could substantially increase our operating losses and reduce the resources available for development activities or any future
sales, marketing or distribution activities. We may not have sufficient financial or other resources to conduct such litigation or proceedings
adequately. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because
of their greater financial resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings
could compromise our ability to compete in the marketplace.

51

 
Table of Contents

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

In addition to seeking patent protection for our product candidates, we rely on trade secrets, including unpatented know how,

technology and other proprietary information, to maintain our competitive position. We limit disclosure of such trade secrets where
possible, but we also seek to protect these trade secrets, in part, by entering into non‑disclosure and confidentiality agreements with parties
who do have access to them, such as our employees, corporate collaborators, outside scientific collaborators, contract manufacturers,
consultants, advisors, and other third parties. We also enter into confidentiality and invention or patent assignment agreements with our
employees and consultants. Despite these efforts, any of these parties may breach the agreements and disclose our proprietary information,
including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim that a party illegally
disclosed or misappropriated a trade secret is difficult, expensive and time‑consuming, and the outcome is unpredictable. In addition, some
courts inside and outside the United States are less willing or unwilling to protect trade secrets. If any of our trade secrets were to be
lawfully obtained or independently developed by a competitor, we would have no right to prevent them, or those to whom they
communicate it, from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or
independently developed by a competitor, our competitive position would be harmed.

Risks Related to Legal Compliance Matters

Our current and future relationships with customers and third-party payors in the United States and elsewhere may be subject, directly
or indirectly, to applicable anti‑kickback, fraud and abuse, false claims, transparency, health information privacy and security and other
healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm,
administrative burdens and diminished profits and future earnings.

Healthcare providers, physicians and third-party payors in the United States and elsewhere will play a primary role in the
recommendation and prescription of any product candidates for which we obtain marketing approval. Our current and future arrangements
with healthcare providers, third-party payors, and customers may expose us to broadly applicable fraud and abuse and other healthcare laws
and regulations, including, without limitation, the federal Anti‑Kickback Statute and the federal False Claims Act, which may constrain the
business or financial arrangements and relationships through which we conduct research, sell, market, and distribute any drugs for which we
obtain marketing approval. In addition, we may be subject to transparency laws and patient privacy regulation by U.S. federal and state
governments and by governments in foreign jurisdictions in which we conduct our business. The applicable federal, state and foreign
healthcare laws and regulations that may affect our ability to operate include:

·

·

·

the federal Anti‑Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, offering,
receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward, or in return for, either the
referral of an individual for, or the purchase, order or recommendation of, any good or service, for which payment may be made
under federal and state healthcare programs, such as Medicare and Medicaid;

federal civil and criminal false claims laws and civil monetary penalty laws, including the federal False Claims Act which can be
enforced by individuals, on behalf of the government, through civil whistleblower or qui tam actions, prohibit individuals or
entities from, among other things, knowingly presenting, or causing to be presented, to the federal government, including the
Medicare and Medicaid programs, claims for payment that are false or fraudulent or making a false statement to avoid, decrease
or conceal an obligation to pay money to the federal government;

the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which imposes, among other things, criminal
and civil liability for executing a scheme to defraud any healthcare benefit program or making false statements relating to
healthcare matters;

52

 
Table of Contents

·

·

·

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and their
respective implementing regulations, which impose, among other things, obligations on certain healthcare providers, health plans,
and healthcare clearinghouses, known as covered entities, as well as their business associates that create, receive, maintain or
transmit individually identifiable health information for or on behalf of a covered entity, with respect to safeguarding the privacy,
security and transmission of individually identifiable health information;

the federal Open Payments program, which requires manufacturers of drugs, devices, biologics and medical supplies for which
payment is available under Medicare, Medicaid or the Children’s Health Insurance Program, with specific exceptions, to report
annually to the Centers for Medicare & Medicaid Services, or CMS, information related to “payments or other transfers of value”
made to physicians, which is defined to include doctors, dentists, optometrists, podiatrists and chiropractors, and teaching
hospitals and applicable manufacturers and applicable group purchasing organizations to report annually to CMS ownership and
investment interests held by physicians and their immediate family members; and

analogous state and foreign laws and regulations, such as state anti‑kickback and false claims laws, which may apply to sales or
marketing arrangements and claims involving healthcare items or services reimbursed by non‑governmental third-party payors,
including private insurers; state and foreign laws that require pharmaceutical companies to comply with the pharmaceutical
industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government or
otherwise restrict payments that may be made to healthcare providers; state and foreign laws that require drug manufacturers to
report information related to payments and other transfers of value to physicians and other healthcare providers, marketing
expenditures, or drug pricing; state and local laws that require the registration of pharmaceutical sales and medical
representatives; and state and foreign laws, such as the General Data Protection Regulation (EU) 2016/679, governing the privacy
and security of health information in certain circumstances, many of which differ from each other in significant ways and often
are not preempted by HIPAA, thus complicating compliance efforts.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations may

involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current
or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations
are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to
significant civil, criminal and administrative penalties, including, without limitation, damages, fines, disgorgement, imprisonment,
exclusion from participation in government healthcare programs, such as Medicare and Medicaid, integrity oversight and reporting
obligations to resolve allegations of non-compliance with these laws, and the curtailment or restructuring of our operations, which could
have a material adverse effect on our business. If any of the physicians or other healthcare providers or entities with whom we expect to do
business, including our collaborators, is found not to be in compliance with applicable laws, it may be subject to significant criminal, civil or
administrative sanctions, including exclusions from participation in government healthcare programs, which also could materially affect our
business.

Recently enacted and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize
our product candidates and affect the prices we may obtain.

In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed

changes regarding the healthcare system that could prevent or delay marketing approval of our product candidates, restrict or regulate
post‑approval activities, and affect our ability to profitably sell any product candidates for which we obtain marketing approval.

Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in
healthcare systems with the stated goals of containing healthcare costs, improving quality, and expanding access. In the United States, the
pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives. In
March 2010, President Obama signed into law the Patient Protection and Affordable Care Act, as amended by the Health Care and
Education Reconciliation Act, or collectively,

53

 
Table of Contents

the PPACA, a sweeping law intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance
remedies against fraud and abuse, add new transparency requirements for the healthcare and health insurance industries, impose new taxes
and fees on the health industry and impose additional health policy reforms.

Among the provisions of the PPACA of importance to our potential product candidates are:

an annual, nondeductible fee on any entity that manufactures or imports specified branded prescription drugs and biologic agents,
apportioned among these entities according to their market share in certain government healthcare programs;

an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and
13.0% of the average manufacturer price for branded and generic drugs, respectively;

expansion of healthcare fraud and abuse laws, including the federal False Claims Act and the federal Anti‑Kickback Statute, new
government investigative powers and enhanced penalties for non‑compliance;

a new Medicare Part D coverage gap discount program, in which manufacturers must now agree to offer 70% point‑of‑sale
discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition
for a manufacturer’s outpatient drugs to be covered under Medicare Part D;

extension of a manufacturer’s Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid
managed care organizations;

expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to
additional individuals and by adding new mandatory eligibility categories for certain individuals with income at or below 133%
of the federal poverty level, thereby potentially increasing a manufacturer’s Medicaid rebate liability;

expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program;

the new requirements under the federal Open Payments program and its implementing regulations;

a new requirement to annually report drug samples that manufacturers and distributors provide to physicians; and

a new Patient‑Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical
effectiveness research, along with funding for such research.

Some of the provisions of the PPACA have yet to be implemented, and there have been judicial and Congressional challenges to certain

aspects of the PPACA, as well as recent efforts by the Trump administration to repeal or replace certain aspects of the PPACA. Since
January 2017, President Trump has signed two Executive Orders and other directives designed to delay the implementation of certain
provisions of the PPACA or otherwise circumvent some of the requirements for health insurance mandated by the PPACA. Concurrently,
Congress has considered legislation that would repeal or repeal and replace all or part of the PPACA. While Congress has not passed
comprehensive repeal legislation, two bills affecting the implementation of certain taxes under the PPACA have been signed into law. The
Tax Cuts and Jobs Act of 2017, or the Tax Act, included a provision which repealed, effective January 1, 2019, the tax-based shared
responsibility payment imposed by the PPACA on certain individuals who fail to maintain qualifying health coverage for all or part of a
year that is commonly referred to as the “individual mandate.” On January 22, 2018, President Trump signed a continuing resolution on
appropriations for fiscal year 2018 that delayed the implementation of certain PPACA-mandated fees, including the so-called “Cadillac” tax
on certain high cost employer-sponsored insurance plans, the annual fee imposed on certain health insurance providers based on market
share, and the medical device excise tax on non-exempt medical devices. The Bipartisan Budget Act of 2018, or the BBA, among other
things, amended the PPACA, effective January 1, 2019, to close the coverage gap in most Medicare drug plans, commonly

54

 
Table of Contents

referred to as the “donut hole.” On December 14, 2018, a Texas U.S. District Court Judge ruled that the PPACA is unconstitutional in its
entirety because the “individual mandate” was repealed by Congress as part of the Tax Act. While the Texas U.S. District Court Judge, as
well as the Trump administration and CMS, have stated that the ruling will have no immediate effect pending appeal of the decision, it is
unclear how this decision, subsequent appeals, and other efforts to repeal and replace the PPACA will impact the PPACA and our business.

In addition, other legislative changes have been proposed and adopted since the PPACA was enacted. These changes include aggregate

reductions to Medicare payments to providers of 2% per fiscal year, which went into effect on April 1, 2013, and, due to subsequent
legislative amendments to the statute, including the BBA, will remain in effect through 2027 unless additional Congressional action is taken.
The American Taxpayer Relief Act of 2012, among other things, further reduced Medicare payments to several providers and increased the
statute of limitations period for the government to recover overpayments to providers from three to five years. These new laws may result in
additional reductions in Medicare and other healthcare funding, which could have a material adverse effect on customers for our drugs, if
approved, and, accordingly, our financial operations.

Further, there has been heightened governmental scrutiny in the United States of pharmaceutical pricing practices in light of the rising

cost of prescription drugs and biologics. Such scrutiny has resulted in several recent Congressional inquiries and proposed and enacted
federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between
pricing and manufacturer patient programs, and reform government program reimbursement methodologies for products. At the federal
level, the Trump administration’s budget proposal for fiscal year 2019 contained further drug price control measures that could be enacted
during the 2019 budget process or in other future legislation, including, for example, measures to permit Medicare Part D plans to negotiate
the price of certain drugs under Medicare Part B, to allow some states to negotiate drug prices under Medicaid, and to eliminate cost sharing
for generic drugs for low-income patients. Moreover, the Trump administration released a “Blueprint” to lower drug prices and reduce out
of pocket costs of drugs that contains additional proposals to increase drug manufacturer competition, increase the negotiating power of
certain federal healthcare programs, incentivize manufacturers to lower the list price of their products, and reduce the out of pocket costs of
drug products paid by consumers. The Department of Health and Human Services, or HHS, has already started the process of soliciting
feedback on some of these measures and, at the same, is immediately implementing others under its existing authority. For example, in
September 2018, CMS announced that it will allow Medicare Advantage plans the option to use step therapy for Part B drugs beginning
January 1, 2019 and, in October 2018, CMS proposed a new rule that would require direct-to-consumer television advertisements of
prescription drugs and biological products, for which payment is available through or under Medicare or Medicaid, to include in the
advertisement the Wholesale Acquisition Cost, or list price, of that drug or biological product. On January 31, 2019, the HHS Office of
Inspector General proposed modifications to the federal Anti-Kickback Statute discount safe harbor for the purpose of reducing the cost of
drug products to consumers which, among other things, if finalized, will affect discounts paid by manufacturers to Medicare Part D plans,
Medicaid managed care organizations and pharmacy benefit managers working with these organizations. While some of these and other
proposed measures may require additional authorization to become effective, Congress and the Trump administration have each indicated
that it will continue to seek new legislative and/or administrative measures to control drug costs. At the state level, legislatures have
increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including
price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency
measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

It is possible that healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and in
additional downward pressure on the reimbursement that we receive for any approved drug. Any reduction in reimbursement from Medicare
or other government healthcare programs may result in a similar reduction in payments from private payors. The implementation of cost
containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize
our drugs.

Legislative and regulatory proposals have been made to expand post‑approval requirements and restrict sales and promotional activities

for drugs. We cannot be sure whether additional legislative changes will be enacted, or whether the FDA regulations, guidance or
interpretations will be changed, or what the impact of such changes on the marketing approvals of our product candidates, if any, may be. In
addition, increased scrutiny by the U.S. Congress of the FDA’s

55

 
Table of Contents

approval process may significantly delay or prevent marketing approval, as well as subject us to more stringent product labeling and
post‑marketing testing and other requirements.

Governments outside the United States tend to impose strict price controls, which may adversely affect our revenue, if any.

In some countries, particularly the countries of the European Union, the pricing of prescription pharmaceuticals is subject to

governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of
marketing approval for a product. To obtain coverage and reimbursement or pricing approval in some countries, we may be required to
conduct a clinical trial that compares the cost‑effectiveness of our product candidate to other available therapies. If reimbursement of our
products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business could be harmed, possibly
materially.

If we fail to comply with environmental, health, and safety laws and regulations, we could become subject to fines or penalties or incur
costs that could harm our business.

We are subject to numerous environmental, health, and safety laws and regulations, including those governing laboratory

procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. Our operations involve the use of
hazardous and flammable materials, including chemicals and biological materials. Our operations also produce hazardous waste products.
We generally contract with third parties for the disposal of these materials and wastes. We cannot eliminate the risk of contamination or
injury from these materials. In the event of contamination or injury resulting from our use of hazardous materials, we could be held liable
for any resulting damages, and any liability could exceed our resources. We also could incur significant costs associated with civil or
criminal fines and penalties for failure to comply with such laws and regulations.

Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our

employees resulting from the use of hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We
do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our storage or
disposal of biological, hazardous or radioactive materials.

In addition, we may incur substantial costs in order to comply with current or future environmental, health, and safety laws and

regulations. These current or future laws and regulations may impair our research, development or production efforts. Our failure to comply
with these laws and regulations also may result in substantial fines, penalties, or other sanctions.

Risks Related to Employee Matters and Managing Our Growth

Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified personnel.

We are highly dependent on the development, clinical, business development, legal, financial, and commercial expertise of our

executive officers. Although we have entered into employment agreements with these individuals, each of them may terminate their
employment with us at any time. We do not maintain “key person” insurance for any of our executives or other employees.

Recruiting and retaining qualified management, scientific, clinical, manufacturing, sales and marketing, and other personnel also

will be critical to our success. The loss of the services of our executive officers or other key employees or consultants could impede the
achievement of our development and commercialization objectives and seriously harm our ability to successfully implement our business
strategy. Furthermore, replacing executive officers and key employees or consultants may be difficult and may take an extended period of
time because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully develop,
gain regulatory approval of and commercialize products. Competition to hire from this limited pool is intense, and we may be unable to hire,
train, retain or motivate these key personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology
companies for similar personnel.

56

 
Table of Contents

We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. In

addition, we rely on consultants and advisors, including scientific, clinical, and commercial advisors, to assist us in formulating our
development and commercialization strategy. Our consultants and advisors may be employed by employers other than us and may have
commitments under consulting or advisory contracts with other entities that may limit their availability to us. If we are unable to continue to
attract and retain high quality personnel, our ability to pursue our growth strategy will be limited.

In the future, we expect to expand our development, regulatory, manufacturing, sales, marketing, and distribution capabilities, and as a
result, we may encounter difficulties in managing our growth, which could disrupt our operations.

In the future, we expect to experience growth in the number of our employees and the scope of our operations, particularly in the
areas of drug development, regulatory affairs, manufacturing, sales, marketing, and distribution. To manage our anticipated future growth,
we must continue to implement and improve our managerial, operational and financial systems, expand our facilities and continue to recruit
and train additional qualified personnel. Due to our limited financial resources and the limited experience of our management team in
managing a company with such anticipated growth, we may not be able to effectively manage the expansion of our operations or recruit and
train additional qualified personnel. The expansion of our operations may lead to significant costs and may divert our management and
business development resources. Any inability to manage growth could delay the execution of our business plans or disrupt our operations.

Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and
requirements, which could expose us to liability and hurt our reputation.

We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees could include intentional failures to

comply with FDA regulations, provide accurate information to the FDA, report financial information or data accurately or disclose
unauthorized activities to us. Employee misconduct also could involve the improper use or misrepresentation of information obtained in the
course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. It is not always possible to identify
and deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown
or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be
in compliance with such laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or
asserting our rights, those actions could have a significant impact on our business and financial results, including the imposition of
significant civil, criminal and administrative penalties, including, without limitation, damages, fines, disgorgement, imprisonment,
exclusion from participation in government healthcare programs, such as Medicare and Medicaid, integrity oversight and reporting
obligations to resolve allegations of non-compliance with these laws, and the curtailment or restructuring of our operations, which could
have a material adverse effect on our business.

Other Risks Related to our Business

In the future, we may conduct a substantial portion of the clinical trials for our product candidates outside of the United States and, if
approved, we intend to seek to market our product candidates abroad through third-party collaborators. Accordingly, we will be subject
to the risks of doing business outside of the United States.

In the future, we may conduct a substantial portion of our clinical trials outside of the United States and, if approved, we intend to

seek to market our product candidates outside of the United States. We are thus subject to risks associated with doing business outside of the
United States. With respect to our product candidates, we may choose to partner with third parties that have direct sales forces and
established distribution systems, in lieu of our own sales force and distribution systems, which would indirectly expose us to these risks.
Our business and financial results in the future

57

 
Table of Contents

could be adversely affected due to a variety of factors associated with conducting development and marketing of our product candidates, if
approved, outside of the United States, including:

·

·

·

·

·

·

·

·

·

·

efforts to develop an international sales, marketing and distribution organization may increase our expenses, divert our
management’s attention from the development of product candidates or cause us to forgo profitable licensing opportunities in
these geographies;

changes in a specific country’s or region’s political and cultural climate or economic condition;

unexpected changes in foreign laws and regulatory requirements;

difficulty of effective enforcement of contractual provisions in local jurisdictions;

inadequate intellectual property protection in foreign countries;

differing payor reimbursement regimes, governmental payors or patient self-pay systems and price controls;

trade‑protection measures, import or export licensing requirements such as Export Administration Regulations promulgated by
the U.S. Department of Commerce and fines, penalties or suspension or revocation of export privileges;

regulations under the U.S. Foreign Corrupt Practices Act and similar foreign anti‑corruption laws;

the effects of applicable foreign tax structures and potentially adverse tax consequences; and

significant adverse changes in foreign currency exchange rates which could make the cost of our clinical trials, to the extent
conducted outside of the United States, more expensive.

Our business and operations would suffer in the event of system failures.

We utilize information technology systems and networks to process, transmit and store electronic information in connection with

our business activities. As use of digital technologies has increased, cyber incidents, including deliberate attacks and attempts to gain
unauthorized access to computer systems and networks, have increased in frequency and sophistication. These threats pose a risk to the
security of our systems and networks and the confidentiality, availability and integrity of our data. There can be no assurance that we will be
successful in preventing cyber-attacks or successfully mitigating their effects.

Despite our implementation of security measures, our internal computer systems and those of our contractors and consultants are
vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war, and telecommunication and electrical
failures. If such an event were to occur and cause interruptions in our operations, it could result in a material disruption to our product
candidate development programs. For example, the loss of clinical trial data from completed, ongoing or planned clinical trials could result
in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any
disruption or security breach were to result in a loss of or damage to our data or applications, or inappropriate disclosure of personal,
confidential or proprietary information, we could incur liability and the further development of any of our product candidates could be
delayed or abandoned.

Risks Related to Ownership of Our Common Stock

An active trading market for our common stock may not continue to develop or be sustained.

Although our common stock is listed on the Nasdaq, we cannot assure you that an active, liquid trading market for our shares will

continue to develop or be sustained. If an active market for our common stock does not continue to

58

 
Table of Contents

develop or is not sustained, it may be difficult for you to sell shares quickly or without depressing the market price for the shares or to sell
your shares at all.

The trading price of the shares of our common stock has been and may continue to be volatile, and you may not be able to resell some or
all of your shares at a desired price.

Since our common stock commenced trading in January 2014, our stock price has been highly volatile, with closing stock prices

ranging from a high of $13.30 per share to a low of $0.39 per share as of March 11, 2019.

The stock market in general and the market for biopharmaceutical companies in particular have experienced extreme volatility that

has often been unrelated to the operating performance of particular companies. As a result of this volatility, investors in our stock may not
be able to sell their common stock at or above the price paid for the shares. The market price for our common stock may be influenced by
many factors, including:

·

·

·

·

·

·

·

·

·

·

·

·

·

·

·

actual or anticipated variations in our operating results;

changes in financial estimates by us or by any securities analysts who might cover our stock;

the timing and results of our clinical trials for any of our product candidates;

failure or discontinuation of any of our development programs;

conditions or trends in our industry;

changes in the structure of healthcare payment systems;

stock market price and volume fluctuations of comparable companies and, in particular, those that operate in the
biopharmaceutical industry;

announcements by us or our competitors of significant acquisitions, strategic partnerships or divestitures;

developments or disputes concerning patent applications, issued patents or other proprietary rights;

announcements of investigations or regulatory scrutiny of our operations or lawsuits filed against us;

capital commitments;

investors’ general perception of our company and our business;

recruitment or departure of key personnel;

announcements and expectations of additional financing efforts; and

sales of our common stock, including sales by our directors and officers or specific stockholders.

We are subject to securities class action and stockholder derivative litigation.

As described in “Item 3. Legal Proceedings” of this Annual Report on Form 10-K, in October and November 2018, we and certain

of our current and former directors and officers were sued in three purported class actions filed in the U.S. District Court for the Eastern
District of Pennsylvania, or the EDPA. In each case, the plaintiffs allege that we and the officers made false and misleading statements in
violation of federal securities laws regarding our business, operations, and prospects, including certain statements made relating to our End-
of-Phase 2 meeting with the FDA. The

59

 
Table of Contents

plaintiffs seek, among other remedies, unspecified damages, attorneys’ fees and other costs. In January 2019, the three lawsuits were
consolidated into one action. On March 6, 2019, the District Court held a hearing to appoint the lead plaintiff and lead counsel, and a
consolidated amended complaint will be filed after such appointments are made. We believe that the lawsuits are without merit, and we
intend to vigorously defend ourselves against the allegations.

In December 2018, a shareholder derivative action was filed against us and certain current and former officers and directors in the
EDPA, and in February 2019, two additional, similar shareholder derivative actions were filed in the U.S. District Court for the District of
Delaware. These cases, which involve similar facts as the consolidated securities lawsuits, assert claims against the individual defendants
for, among other things, breach of fiduciary duty, waste of corporate assets, violations of the federal securities laws, and unjust enrichment,
and they make a number of demands, including for monetary damages and other equitable and injunctive relief. Two of the derivative
actions have been stayed in favor of the consolidated securities lawsuits, and we expect that the third derivative action will be stayed as well.
Furthermore, such litigation could cause us to incur substantial costs and divert management’s attention and resources from the operation of
our business. These factors may materially and adversely affect the market price of our common stock.

If equity research analysts do not continue to publish research or reports or publish unfavorable research or reports about us, our
business or our industry, our stock price and trading volume could decline.

The trading market for our common stock is influenced by the research and reports that equity research analysts publish about us
and our business. As a relatively new public company, we have only limited research coverage by equity research analysts. Equity research
analysts may elect not to initiate or continue to provide research coverage of our common stock, and such lack of research coverage may
adversely affect the market price of our common stock. We have no control over the analysts or the content and opinions included in their
reports. The price of our stock could decline if one or more equity research analysts downgrade our stock or issue other unfavorable
commentary or research.

If one or more equity research analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our

stock could decrease, which in turn could cause our stock price or trading volume to decline.

Sales of a substantial number of shares of our common stock could cause the market price of our common stock to drop significantly,
even if our business is doing well.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. If our stockholders sell,
or the market perceives that our stockholders intend to sell, substantial amounts of our common stock in the public market, the market price
of our common stock could decline significantly.

In addition, we have filed registration statements on Form S‑8 registering the issuance of shares of common stock subject to

options or other equity awards issued or reserved for future issuance under our equity incentive plans. Shares registered under these
registration statements on Form S‑8 are available for sale in the public market subject to vesting arrangements and exercise of existing
options, the grant of new options in the future, and the restrictions of Rule 144 in the case of our affiliates.

The issuance of additional stock in connection with financings, acquisitions, investments, our stock incentive plans or otherwise will
dilute all other stockholders.

Our amended and restated certificate of incorporation authorizes us to issue up to 200,000,000 shares of common stock and up to

5,000,000 shares of preferred stock with such rights and preferences as may be determined by our board of directors. Subject to compliance
with applicable rules and regulations, we may issue our shares of common stock or securities convertible into our common stock from time
to time in connection with a financing, acquisition, investment, our stock incentive plans or otherwise. Any such issuance could result in
substantial dilution to our existing stockholders and cause the trading price of our common stock to decline.

60

 
Table of Contents

Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited.

We have incurred substantial losses during our history. We do not anticipate generating revenue from sales of products for the

foreseeable future, if ever, and we may never achieve profitability. To the extent that we continue to generate tax losses, unused losses will
carry forward to offset future taxable income, if any, until such unused losses expire. Under Section 382 of the Internal Revenue Code of
1986, as amended, if a corporation undergoes an “ownership change,” which is generally defined as a greater than 50% change, by value, in
its equity ownership over a three‑year period, the corporation’s ability to use its pre‑change net operating loss carryforwards and other
pre‑change tax attributes to offset its post‑change income may be limited. We have not completed our analysis to determine what, if any,
impact any prior ownership change has had on our ability to utilize our net operating loss carryforwards. In addition, we may experience
ownership changes in the future as a result of subsequent shifts in our stock ownership. As of December 31, 2018, we had federal net
operating loss carryforwards of approximately $65.5 million that could be limited if we have experienced, or if in the future we experience,
an ownership change.

Provisions in our corporate charter documents and under Delaware law may prevent or frustrate attempts by our stockholders to change
our management and hinder efforts to acquire a controlling interest in us, and the market price of our common stock may be lower as a
result.

There are provisions in our amended and restated certificate of incorporation and amended and restated bylaws that may make it
difficult for a third party to acquire, or attempt to acquire, control of our company, even if a change in control was considered favorable by
you and other stockholders. For example, our board of directors has the authority to issue up to 5,000,000 shares of preferred stock. The
board of directors can fix the price, rights, preferences, privileges, and restrictions of the preferred stock without any further vote or action
by our stockholders. The issuance of shares of preferred stock may delay or prevent a change in control transaction. As a result, the market
price of our common stock and the voting and other rights of our stockholders may be adversely affected. An issuance of shares of preferred
stock may result in the loss of voting control to other stockholders.

Our charter documents also contain other provisions that could have an anti‑takeover effect, including:

only one of our three classes of directors will be elected each year;

stockholders are not entitled to remove directors other than by a 66 2/3% vote and only for cause;

stockholders are not permitted to take actions by written consent;

stockholders cannot call a special meeting of stockholders; and

stockholders must give advance notice to nominate directors or submit proposals for consideration at stockholder meetings.

·

·

·

·

·

In addition, we are subject to the anti‑takeover provisions of Section 203 of the Delaware General Corporation Law, which regulates
corporate acquisitions by prohibiting Delaware corporations from engaging in specified business combinations with particular stockholders
of those companies. These provisions could discourage potential acquisition proposals and could delay or prevent a change in control
transaction. They could also have the effect of discouraging others from making tender offers for our common stock, including transactions
that may be in your best interests. These provisions may also prevent changes in our management or limit the price that investors are willing
to pay for our stock.

We are an “emerging growth company” and as a result of the reduced disclosure and governance requirements applicable to emerging
growth companies, our common stock may be less attractive to investors.

We are an “emerging growth company” as defined in the JOBS Act, and we intend to take advantage of some of the exemptions

from reporting requirements that are applicable to other public companies that are not emerging growth companies, including not being
required to comply with the auditor attestation requirements of Section 404 of

61

 
Table of Contents

the Sarbanes‑Oxley Act of 2002, or Sarbanes‑Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic
reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and
stockholder approval of any golden parachute payments not previously approved. We cannot predict if investors will find our common
stock less attractive because we will rely on these exemptions. If some investors find our common stock less attractive as a result, there may
be a less active trading market for our common stock and our stock price may be more volatile. We may take advantage of these reporting
exemptions until we are no longer an emerging growth company. We will remain an emerging growth company until the earliest of (a)
December 31, 2019, (b) the last day of the fiscal year in which we have total annual gross revenue of at least $1.0 billion, (c) the last day of
the fiscal year in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by
non‑affiliates exceeds $700.0 million as of the prior June 30th, and (d) any date on which we have issued more than $1.0 billion in
non‑convertible debt during the prior three‑year period.

Under Section 107(b) of the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards until
such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or
revised accounting standards and, therefore, we will be subject to the same new or revised accounting standards as other public companies
that are not emerging growth companies.

If we fail to maintain proper and effective internal controls, our ability to produce accurate financial statements on a timely basis could
be impaired.

We are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act, the

Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act, and the rules and regulations of Nasdaq. The Sarbanes‑Oxley Act
requires, among other things, that we maintain effective disclosure controls and procedures and internal controls over financial reporting.
Effective internal controls over financial reporting are necessary for us to provide reliable financial reports and, together with adequate
disclosure controls and procedures, are designed to prevent fraud. For our fiscal year ended December 31, 2018, we are obligated to perform
system and process evaluation and testing of our internal controls over financial reporting to allow management to report on the
effectiveness of our internal controls over financial reporting in our Form 10-K filing for that year, as required by Section 404(a) of the
Sarbanes-Oxley Act. We will continue to incur substantial additional professional fees and internal costs to expand our accounting and
finance functions and expend significant management efforts. We may discover weaknesses in our system of internal financial and
accounting controls and procedures that could result in a material misstatement of our financial statements. Our internal control over
financial reporting will not prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can
provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all
control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all
control issues and instances of fraud will be detected.

If we are not able to comply with the requirements of Section 404(a) of the Sarbanes-Oxley Act in a timely manner, or if we are

unable to implement or maintain proper and effective internal controls, we may not be able to produce timely and accurate financial
statements. If that were to happen, the market price of our stock could decline and we could be subject to sanctions or investigations by the
stock exchange on which our common stock is listed, the Securities and Exchange Commission, or SEC, or other regulatory authorities. In
addition, any testing by us conducted in connection with Section 404(a) of the Sarbanes-Oxley Act, or the subsequent testing by our
independent registered public accounting firm conducted in connection with Section 404(b) of the Sarbanes-Oxley Act once we no longer
qualify as an “emerging growth company,” may reveal deficiencies in our internal controls over financial reporting that are deemed to be
material weaknesses; or may require prospective or retroactive changes to our financial statements or identify other areas for further
attention or improvement.

We are required to disclose changes made in our internal control procedures on a quarterly basis and our management is required
to assess the effectiveness of these controls annually. However, for as long as we are an “emerging growth company” under the JOBS Act,
our independent registered public accounting firm will not be required to attest to the effectiveness of our internal control over financial
reporting pursuant to Section 404(b). If and when we cease to be an “emerging growth company,” an assessment of the effectiveness of our
internal controls by our

62

 
Table of Contents

independent registered public accounting firm will be very expensive and could detect problems that our management’s assessment might
not.

Because we do not anticipate paying any cash dividends on our common stock in the foreseeable future, capital appreciation, if any, will
be your sole source of gains and you may never receive a return on your investment.

You should not rely on an investment in our common stock to provide dividend income. We have not declared or paid cash

dividends on our common stock to date and have no plans to pay cash dividends in the foreseeable future. We currently intend to retain our
future earnings, if any, to fund the development and growth of our business. In addition, the terms of our term loan credit facility with
Oxford Finance LLC and Pacific Western Bank prohibits us from paying cash dividends. As a result, capital appreciation, if any, of our
common stock will be your sole source of gain for the foreseeable future. Investors seeking cash dividends should not purchase our common
stock.

We incur costs and demands upon management as a result of being a public company.

As a public company listed in the United States, we are incurring, and will continue to incur, significant legal, accounting and other
costs, particularly after we cease to be an “emerging growth company.” These costs could negatively affect our financial results. In addition,
changing laws, regulations and standards relating to corporate governance and public disclosure, including regulations implemented by the
SEC and stock exchanges, may increase legal and financial compliance costs and make some activities more time consuming. These laws,
regulations and standards are subject to varying interpretations and, as a result, their application in practice may evolve over time as new
guidance is provided by regulatory and governing bodies. We intend to invest resources to comply with evolving laws, regulations and
standards, and this investment may result in increased general and administrative expenses and a diversion of management’s time and
attention from revenue‑generating activities to compliance activities. If, notwithstanding our efforts to comply with new laws, regulations
and standards, we fail to comply, regulatory authorities may initiate legal proceedings against us and our business may be harmed.

Failure to comply with these rules also might make it more difficult for us to obtain some types of insurance, including directors’
and officers’ liability insurance, and we might be forced to accept reduced policy limits and coverage or incur substantially higher costs to
obtain the same or similar coverage. The impact of these events could also make it more difficult for us to attract and retain qualified persons
to serve on our board of directors, on committees of our board of directors or as members of senior management.

ITEM 1B. UNRESOLVED STAFF COMMENTS 

None.

ITEM 2. PROPERTIES 

Our principal office is located at 955 Chesterbrook Boulevard, Chesterbrook, Pennsylvania, where we currently lease

approximately 8,231 square feet of developed office space on the first floor and 40,565 square feet of developed office space on the second
floor. The lease term for this space extends through May 2028. On October 11, 2018, we entered into an agreement with The Vanguard
Group, Inc., or Vanguard, whereby Vanguard agreed to sublease the 40,565 square feet of space on the second floor for an initial term of 37
months. Vanguard has an option to extend the sublease term for 3 years, and a second option to extend the sublease until November 30,
2027. The sublease provides for rent abatement for the first month of the term; thereafter, the rent payable to us by Vanguard under the
sublease is (i) $0.50 less during months 2 through 13 of the sublease and (ii) in month 14 and thereafter of the sublease, $1.00 less than the
base rent payable by us under our master lease with Chesterbrook Partners, L.P. Vanguard also is responsible for paying to us all tenant
energy costs, annual operating costs, and annual tax costs attributable to the subleased space during the term of the sublease.

In October 2017, we terminated our lease related to vivarium space in Exton, Pennsylvania, under an agreement expiring on

December 31, 2018. We incurred termination fees equivalent to three months’ rent, totaling less than $0.1 million, in relation to the early
termination of this agreement. Additionally, in November 2017, we provided notice of

63

 
Table of Contents

our intent to terminate our facility lease of approximately 16,714 square feet of office and laboratory space in King of Prussia, Pennsylvania,
under an agreement that expires in September 2020. We paid the landlord a $0.15 million termination fee on the date we exercised the
termination option. This lease was deemed terminated on August 15, 2018.

ITEM 3. LEGAL PROCEEDINGS 

In October and November 2018, the Company and certain of its current and former officers were sued in three purported class
actions filed in the U.S. District Court for the Eastern District of Pennsylvania, or the EDPA. In each case, the plaintiffs allege that the
Company and the officers made false and misleading statements in violation of federal securities laws regarding the Company’s business,
operations, and prospects, including certain statements made relating to the Company’s End-of-Phase 2 meeting with the FDA. The
plaintiffs seek, among other remedies, unspecified damages, and attorneys’ fees and other costs. In January 2019, the three lawsuits were
consolidated into one action. On March 6, 2019, the District Court held a hearing to appoint the lead plaintiff and lead counsel, and a
consolidated amended complaint will be filed after such appointments are made. The Company believes that the lawsuits are without merit,
and it intends to vigorously defend itself against the allegations.

In December 2018, a shareholder derivative action was filed on behalf of the Company and against certain current and former
officers and directors in the EDPA, and in February 2019, two additional, similar shareholder derivative actions were filed in the U.S.
District Court for the District of Delaware. These cases, which involve similar facts as the consolidated securities lawsuits, assert claims
against the individual defendants for, among other things, breach of fiduciary duty, waste of corporate assets, violations of the federal
securities laws, and unjust enrichment, and they make a number of demands, including for monetary damages and other equitable and
injunctive relief. Two of the derivative actions have been stayed in favor of the consolidated securities lawsuits, and the Company expects
that the third derivative action will be stayed as well.

Except as described above, the Company is not involved in any legal proceeding that it expects to have a material effect on its

business, financial condition, results of operations and cash flows.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS 

You should read the following discussion and analysis of our financial condition and results of operations together with our

financial statements and related notes appearing in this Annual Report. Some of the information contained in this discussion and analysis
or set forth elsewhere in this Annual Report, including information with respect to our plans and strategy for our business and related
financing, includes forward‑looking statements that involve risks and uncertainties. As a result of many factors, including those factors set
forth in the “Risk Factors” section of this Annual Report, our actual results could differ materially from the results described in or implied
by the forward‑looking statements contained in the following discussion and analysis.

Overview

Using our proprietary product platform, we have identified and are developing the following product candidates:

· Oliceridine injection: We are developing oliceridine, a G protein biased mu-opioid receptor, or MOR, ligand, for the

management of moderate-to-severe acute pain in hospitals or other controlled clinical settings where intravenous, or IV,
administration is warranted. We have completed two pivotal Phase 3 efficacy studies (APOLLO 1 and APOLLO 2) of
oliceridine in moderate-to-severe acute pain following bunionectomy and abdominoplasty, respectively. In both studies, all
dose regimens achieved their primary endpoint of statistically greater analgesic efficacy than placebo, as measured by
responder rate. We also have completed Phase 3 open-label safety study (ATHENA) in which 768 patients were administered
oliceridine to manage pain associated with a wide range of procedures and diagnoses. In late 2017, we submitted the
oliceridine new drug application, or NDA, to the United States Food and Drug Administration, or FDA. On November 2,
2018, the FDA issued a complete response letter, or CRL, with respect to our NDA for oliceridine. In the CRL, the FDA
requested additional clinical data on the QT interval and indicated that the submitted safety database was not of adequate size
for the proposed labeling. The FDA also requested certain additional nonclinical data and validation reports. On January 28,
2019, we announced the receipt of the official Type A meeting minutes from the FDA regarding the CRL wherein the FDA
agreed that our current safety database will support labeling at a maximum daily dose of 27 mg. The FDA also agreed that we
can conduct a study in healthy volunteers to collect the requested QT interval data and that the study should include placebo-
and positive-control arms. We have submitted a detailed protocol and analysis plan to the FDA and, following receipt of
FDA feedback, anticipate initiating the study in the first half of 2019. To address remaining items in the CRL, the FDA
indicated that we should include supporting nonclinical data related to the characterization of the 9662 metabolite and the
remaining product validation reports when we resubmit the oliceridine NDA.

·

·

TRV250: We are developing TRV250, a G protein biased delta-opioid receptor, or DOR, ligand, as a compound with a
potential first-in-class mechanism for the treatment of acute migraine. TRV250 also may have utility in a range of other
central nervous system, or CNS, indications. Because TRV250 selectively targets the DOR, we believe it will not have the
addiction liability of conventional opioids or other mu-opioid related adverse effects like those seen with morphine or
oxycodone. In June 2018, we announced the successful completion of our first-in-human Phase 1 study of TRV250. Data
from this healthy volunteer study showed safety, tolerability, and pharmacokinetics supporting the advancement of TRV250
to Phase 2 proof of concept evaluation in patients.

TRV734: We also have identified and have completed the initial Phase 1 studies for TRV734, a new chemical entity, or
NCE, targeting the same novel mechanism of action at the MOR as oliceridine. TRV734 was designed to be orally available,
and its mechanism of action suggests it may offer valuable benefits for two distinct areas of important unmet medical need:
acute and chronic pain, and maintenance therapy for patients with opioid use disorder. We are collaborating with the National
Institute on Drug Abuse, or NIDA, to further evaluate TRV734 for the management of opioid use disorder. We intend to
continue to focus our efforts for TRV734 on securing a development and commercialization partner for this asset.

65

 
Table of Contents

We also are evaluating a set of novel S1P modulators that may offer a new, non-opioid approach to managing chronic pain. In the

fourth quarter of 2018, we identified a new product candidate, TRV045, a novel S1P modulator that we believe may offer a new, non-opioid
approach to managing chronic pain. We anticipate beginning investigational new drug, or IND, enabling work in 2019, and we will continue
to evaluate the progression of this asset to an IND, either by ourselves or with a partner.

Since our incorporation in late 2007, our operations have included organizing and staffing our company, business planning, raising
capital, and discovering and developing our product candidates. We have financed our operations primarily through private placements and
public offerings of our equity securities and debt borrowings. As of December 31, 2018, we had an accumulated deficit of $388.3 million.
Our net loss was $30.8 million, $71.9 million and $103.0 million for the years ended December 31, 2018, 2017 and 2016, respectively. Our
ability to become and remain profitable depends on our ability to generate revenue or sales. We do not expect to generate significant revenue
or sales unless and until we or a collaborator obtain marketing approval for and commercialize oliceridine, TRV250, or TRV734.

We expect to incur significant expenses and operating losses for the foreseeable future as we continue the development and clinical

trials of, seek regulatory approval for, and prepare for commercialization of our product candidates and repay our outstanding loan
obligations. To secure approval of oliceridine, we may be required to conduct additional clinical studies. The amount and timing of such
studies are unknown. We will need to obtain substantial additional funding in connection with our continuing operations. We will seek to
fund our operations through the sale of equity, debt financings or other sources, including potential collaborations. However, we may be
unable to raise additional funds or enter into such other agreements when needed on favorable terms, or at all. If we fail to raise capital or
enter into such other arrangements as, and when, needed, we may have to significantly delay, scale back or discontinue our operations,
development programs, and/or any future commercialization efforts.

Recent Developments

Restructuring

On November 8, 2018, upon the approval of our Board of Directors, we announced a restructuring of approximately one-third of

our workforce, or 14 employees, as well as other cost saving initiatives intended to lower our annualized net operating cash burn. We
completed the restructuring on December 31, 2018. We have determined that the total costs related to the restructuring were approximately
$1.4 million, all of which is expected to result in future cash outlays, primarily related to severance costs and benefit-related expenses. We
recorded these charges in the fourth quarter of 2018. 

Sublease

On October 11, 2018, we entered into an agreement with The Vanguard Group, Inc., or Vanguard, whereby Vanguard agreed to
sublease 40,565 square feet of space currently rented by us in Chesterbrook, Pennsylvania, for an initial term of 37 months. Vanguard has
an option to extend the sublease term for 3 years, and a second option to extend the sublease until November 30, 2027. The sublease
provides for rent abatement for the first month of the term; thereafter, the rent payable to us by Vanguard under the sublease is (i) $0.50 less
during months 2 through 13 of the sublease and (ii) in month 14 of the sublease and thereafter, $1.00 less than the base rent payable by us
under our master lease with Chesterbrook Partners, L. P. Vanguard also is responsible for paying to us all tenant energy costs, annual
operating costs, and annual tax costs attributable to the subleased space during the term of the sublease.

Litigation

In October and November 2018, we and certain of our current and former officers and directors were sued in three purported class
actions filed in the U.S. District Court for the Eastern District of Pennsylvania, or the EDPA. In each case, the plaintiffs allege that we and
the officers made false and misleading statements in violation of federal securities laws regarding our business, operations, and prospects,
including certain statements made relating to our End-of-Phase 2 meeting with the FDA. The plaintiffs seek, among other remedies,
unspecified damages, attorneys’ fees and other costs. In January 2019, the three lawsuits were consolidated into one action. On March 6,
2019, the District Court

66

 
Table of Contents

held a hearing to appoint the lead plaintiff and lead counsel, and a consolidated amended complaint will be filed after such appointments are
made. We believe that the lawsuits are without merit, and we intend to vigorously defend ourselves against the allegations.

 In December 2018, a shareholder derivative action was filed against us and certain current and former officers and directors in the

EDPA, and in February 2019, two additional, similar shareholder derivative actions were filed in the U.S. District Court for the District of
Delaware. These cases, which involve similar facts as the consolidated securities lawsuits, assert claims against the individual defendants
for, among other things, breach of fiduciary duty, waste of corporate assets, violations of the federal securities laws, and unjust enrichment,
and they make a number of demands, including for monetary damages and other equitable and injunctive relief. Two of the derivative
actions have been stayed in favor of the consolidated securities lawsuits, and we expect that the third derivative action will be stayed as well.

Equity Offering

On January 29, 2019, we entered into securities purchase agreements with two institutional investors wherein we agreed to sell to
the investors an aggregate of 10,000,000 shares of our common stock, at an offering price of $1.00 per share, in a registered direct offering
made pursuant to our existing registration statement on Form S-3. The net proceeds to us from the offering were approximately $9.2 million,
after deducting fees and the expenses of the placement agent. We intend to use the net proceeds from the offering primarily for the
development of oliceridine and for general corporate purposes.

Pursuant to a letter agreement dated January 28, 2019, or the Engagement Letter, we engaged H.C. Wainwright & Co., LLC, or

Wainwright, to act as our exclusive placement agent in connection with the issuance and sale of the shares. We paid Wainwright 7.0% of the
aggregate gross proceeds in the offering and $50,000 for certain expenses, and we issued warrants to purchase 500,000 shares of common
stock to certain designees of Wainwright. These warrants have a term of five years, are immediately exercisable and have an exercise price
of $1.25 per share. The Engagement Letter also includes indemnification obligations of us and other provisions customary for transactions
of this nature.

Senior Secured Tranched Term Loan Credit Facility

In September 2014, we entered into a loan and security agreement with Oxford Finance LLC and Pacific Western Bank, or the

lenders, pursuant to which they agreed to lend us up to $35.0 million in a three-tranche series of term loans (Term Loans A, B, and C).
Upon initially entering into the agreement, we borrowed $2.0 million under Term Loan A. On April 13, 2015, we amended the agreement
with the lenders to change the draw period for Term Loan B. On December 23, 2015, we further amended the agreement with the lenders to,
among other things, change the draw period for Term Loan C, modify the interest only period, and modify the maturity date of the loan. In
December 2015, we borrowed the Term Loan B tranche of $16.5 million. Our ability to draw an additional $16.5 million under Term Loan
C was subject to the satisfaction of one or more specified triggers related to the results of our Phase 2b clinical trial of TRV027. Although
those triggers were not attained, in December 2016, we and the lenders modified the terms and conditions under which we could exercise an
option to draw $10.0 million of Term Loan C. In March 2017, we borrowed the Term Loan C tranche of $10.0 million.

Borrowings under Terms Loans A and B accrue interest at a fixed rate of 6.50% per annum. Borrowings under Term Loan C
accrue interest at a fixed rate of 6.98% per annum. We were required to make payments of interest only on borrowings under the loan
agreement on a monthly basis through and including January 1, 2018; as of January 1, 2018, payments of principal in equal monthly
installments and accrued interest have been and will be due until the loan matures on March 1, 2020. As of December 31, 2018, there was
$15.8 million aggregate principal balance outstanding under the term loans. Upon the last payment date of the amounts borrowed under the
agreement, we will be required to pay a final payment fee equal to 6.6% of the aggregate amounts borrowed. In addition, if we repay Term
Loan A, Term Loan B, or Term Loan C prior to the applicable maturity date, we will pay the lenders a prepayment fee of 1.0% of each of
Term Loans A and B, and 2.0% of Term Loan C, if the prepayment occurs on or between April 1, 2018 and March 31, 2019, and 1.0% of
Term Loan C, if the prepayment occurs on or after April 1, 2019.

Table of Contents

Our obligations are secured by a first priority security interest in substantially all of our assets, including our cash and cash

equivalents and marketable securities, but excluding our intellectual property (together, the collateral). In addition, we have agreed not to
pledge or otherwise encumber our intellectual property, with specified exceptions. Upon an event of default, the lenders have the right to
foreclose upon the available collateral, including our existing cash and cash equivalents and marketable securities.

In connection with entering into the original agreement, we issued to the lenders and placement agent warrants to purchase an

aggregate of 7,678 shares of our common stock, of which 5,728 shares remain outstanding as of December 31, 2018. These warrants are
exercisable immediately and have an exercise price of $5.8610 per share. The warrants may be exercised on a cashless basis and will
terminate on the earlier of September 19, 2024 or the closing of a merger or consolidation transaction in which we are not the surviving
entity. In connection with the draw of Term Loan B, we issued to the lenders and placement agent additional warrants to purchase an
aggregate of 34,961 shares of our common stock. These warrants have substantially the same terms as those noted above, and have an
exercise price of $10.6190 per share and an expiration date of December 23, 2025. In connection with the draw of Term Loan C, we issued
to the lenders and placement agent additional warrants to purchase an aggregate of 62,241 shares of our common stock. These warrants
have substantially the same terms as those noted above, and have an exercise price of $3.6150 per share and an expiration date of
March 31, 2027. These detachable warrant instruments have qualified for equity classification and have been allocated upon the relative fair
value of the base instrument and the warrants, according to the guidance of ASC 470‑20‑25‑2.

Critical Accounting Policies and Significant Judgments and Estimates

The preparation of our consolidated financial statements requires us to make estimates and assumptions that affect the reported

amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of our financial statements, as well as the
reported revenues and expenses during the reported periods. We base our estimates on historical experience and on various other factors
that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of
assets and liabilities that are not apparent from other sources. Actual results may differ from these estimates under different assumptions or
conditions.

A summary of our significant accounting policies appears in the notes to our audited consolidated financial statements for the year

ended December 31, 2018 included in this Annual Report on Form 10‑K. However, we believe that the following accounting policies are
important to understanding and evaluating our reported financial results, and we have accordingly included them in this discussion.

Research and Development

In October 2017, we announced an updated strategy to focus our resources on the potential approval and commercialization of
oliceridine in the United States. With this strategic repositioning, we halted our investment in early stage research. We have completed a
first-in-human Phase 1 trial of TRV250, which showed safety, tolerability, and pharmacokinetics supporting the advancement of TRV250 to
Phase 2 proof of concept evaluation in patients.

Research and development costs are charged to expense as incurred. Research and development costs include, but are not limited
to, personnel expenses, clinical trial supplies, fees for clinical trial services, manufacturing costs, consulting costs, and allocated overhead,
including rent, equipment, depreciation, and utilities.

Costs for certain development activities, such as clinical trials, are recognized based on an evaluation of the progress to completion
of specific tasks using data such as subject enrollment, clinical site activations or information provided to us by our vendors with respect to
their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the
pattern of costs incurred, and are reflected in the financial statements as prepaid or accrued research and development expense, as the case
may be.

As part of the process of preparing our financial statements, we are required to estimate our expenses resulting from our
obligations under contracts with vendors, clinical research organizations and consultants, and under clinical site agreements in connection
with conducting clinical trials. The financial terms of these contracts are subject to

68

 
Table of Contents

negotiations, which vary from contract to contract and may result in payment flows that do not match the periods over which materials or
services are provided under such contracts. Our objective is to reflect the appropriate trial expenses in our financial statements by matching
those expenses with the period in which services are performed and efforts are expended. We may account for these expenses according to
the progress of the trial as measured by subject progression and the timing of various aspects of the trial. We determine accrual estimates
through financial models taking into account discussion with applicable personnel and outside service providers as to the progress or state of
consummation of trials, or the services completed. During the course of a clinical trial, we adjust our clinical expense recognition if actual
results differ from estimates. We make estimates of our accrued expenses as of each balance sheet date based on the facts and circumstances
known to us at that time. Our clinical trial accruals are dependent upon the timely and accurate reporting of contract research organizations
and other third-party vendors. Although we do not expect our estimates to be materially different from amounts actually incurred, our
understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may
result in us reporting amounts that are too high or too low for any particular period. For the years ended December 31, 2018, 2017, and
2016, there were no material adjustments to our prior period estimates of accrued expenses for clinical trials.

Stock‑Based Compensation

At December 31, 2018, we had two stock-based compensation plans, which are more fully described in Note 7. We have applied

the fair value recognition provisions of Financial Accounting Standards Board Accounting Standards Codification Topic 718,
Compensation — Stock Compensation, or ASC 718, to account for stock-based compensation for employees. We recognize compensation
costs related to stock options granted to employees based on the estimated fair value of the awards on the date of grant.

We have equity incentive plans under which various types of equity-based awards including, but not limited to, incentive stock

options, non-qualified stock options, and restricted stock awards, may be granted to employees, non-employee directors, and non-employee
consultants. We also have an inducement plan under which various types of equity-based awards, including non-qualified stock options and
restricted stock awards, may be granted to new employees.

For stock options granted to employees and directors, we recognize compensation expense for all stock-based awards based on the
estimated grant-date fair values. For restricted stock awards to employees, the fair value is based on the closing price of our common stock
on the date of grant. The value of the portion of the award that is ultimately expected to vest is recognized as expense ratably over the
requisite service period. The fair value of stock options is determined using the Black-Scholes option pricing model. We utilize a dividend
yield of zero based on the fact that we have never paid cash dividends and have no current intention of paying cash dividends. As of fiscal
year ended December 31, 2016, we adopted the forfeiture rate methodology change in accordance with ASU 2016-09 to record forfeitures as
they occur.

Stock-based compensation expense related to restricted stock units granted to employees is recognized based on the grant-date fair
value of each award and recorded as expense over the vesting period using the straight-line method. Forfeitures are recorded as they occur.

See Note 7 for a discussion of the assumptions we used in determining the grant date fair value of options granted under the

Black‑Scholes option pricing model, as well as a summary of the stock option activity under our stock‑based compensation plan for
all years presented.

JOBS Act

The Jumpstart Our Business Startups Act of 2012, or the JOBS Act, contains provisions that, among other things, reduce reporting
requirements for an “emerging growth company.” As an emerging growth company, we have elected to not take advantage of the extended
transition period afforded by the JOBS Act for the implementation of new or revised accounting standards and, as a result, will comply with
new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth
companies.

The revenue recognized primarily relates to the upfront payments received at inception of the licensing agreements in South Korea

and China that the Company entered into in 2018.

General and administrative expense

General and administrative expenses consist principally of salaries and related costs for personnel in our executive, finance,

commercial, and other administrative areas, including expenses associated with stock‑based compensation and travel. Other general and
administrative expenses include professional fees for legal, market research, consulting, and accounting services.

General and administrative expenses decreased by $0.7 million, or 3%, for the year ended December 31, 2018 compared to the
same period in 2017, primarily as a result of decreases in bonus and stock-based compensation expenses and oliceridine market research
expenditures, offset by higher employee separation payments in 2018 and increased rent and related expenses in 2018 following the
relocation of our corporate headquarters to Chesterbrook, Pennsylvania in July 2017.

Research and development expense

Research and development expenses consist primarily of costs incurred for research and the development of our product
candidates, including costs associated with the regulatory approval process. In addition, research and development expenses include salaries
and related costs for our research and development personnel and stock-based compensation expense and travel expenses for such
individuals.

Research and development costs are expensed as incurred and are tracked by discovery program and subsequently by product

candidate once a product candidate has been selected for development. We record costs for some development activities, such as clinical
trials, based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations or
information provided to us by our vendors.

Research and development expenses decreased by $33.2 million, or 68% in 2018 as compared to 2017. The following table

The decrease in research and development expenses during the year ended December 31, 2018 was primarily driven by lower

oliceridine expenditures following the completion of the oliceridine Phase 3 clinical program in 2017. In addition, personnel-related
expenditures and other research and development expenses decreased in 2018 as a result of the October 2017 restructuring and reduction in
force, which eliminated our early stage research program.

Restructuring expense

On November 8, 2018, upon the approval of the Board of Directors, we announced a workforce restructuring of approximately
one-third of our workforce, or 14 employees, as well as other cost saving initiatives intended to lower our annualized net operating cash
burn. We completed the restructuring on December 31, 2018. We have determined that the total costs related to the restructuring are
approximately $1.4 million, all of which is expected to result in future cash outlays, primarily related to severance costs and benefit-related
expenses. We recorded these charges in the fourth quarter of 2018. As a result of such restructuring in 2018, restructuring expenses
decreased by $0.3 million, or 20%, for the year ended December 31, 2018 compared to the same period in 2017, when we announced a
restructuring and reduction in force of 21 employees, primarily in the research and development area, as well as other cost saving initiatives,
as further discussed below.

Other income (expense)

Other income increased by $1.9 million, or 131%, during the year ended December 31, 2018 compared to the same period in 2017,

primarily due to a decrease in interest expense associated with lower principal balances during the principal repayment term, income
associated with business development activities, sublease income from Vanguard, an increase in interest income associated with higher
interest rates and an increase in funds received from the sales of Pennsylvania research and development tax credits in 2018, as compared to
2017.

We have historically derived revenue principally from research grants and collaboration arrangements. In March 2015, we signed a

letter agreement with Allergan plc pursuant to which it paid us $10.0 million to fund the expansion of our Phase 2b trial of TRV027 from
500 patients to 620 patients. The collaboration revenue was recorded on a straight-line basis over the remaining period of the trial and was
fully recognized as of June 30, 2016.

General and administrative expense

General and administrative expenses increased by $3.6 million, or 22%, for the year ended December 31, 2017 compared to the

same period in 2016, primarily as a result of increased headcount and associated salary, bonus and stock compensation expenses, oliceridine
market research expenditures, and increased facility expenditures associated with the relocation of our corporate headquarters to
Chesterbrook, Pennsylvania, in July 2017.

Research and development expense

Research and development expenses decreased by $41.0 million, or 46%, for the year ended December 31, 2017 compared to the

same period in 2016. The following table summarizes our research and development expenses (in thousands):

The decrease in research and development expenses during the year ended December 31, 2017 was due to decreased expenditures
upon completion of the oliceridine Phase 3 clinical program and the second quarter 2016 completion of a TRV027 Phase 2b clinical trial in
AHF.

Restructuring expense

On October 11, 2017, upon the approval of our board of directors, we announced a restructuring and reduction in force of
approximately 30% of our workforce, or 21 employees, as well as other cost saving initiatives. The Company incurred pre-tax restructuring
charges of $1.8 million during the year ended December 31, 2017, primarily related to severance and lease termination payments for our
office and laboratory space in King of Prussia, Pennsylvania and vivarium space in Exton, Pennsylvania.

Other income (expense)

Other expense increased by $0.8 million, or 108%, during the year ended December 31, 2017 compared to the same period in

2016, primarily due to additional interest expense related to our Term Loan C tranche of $10.0 million that was drawn in December 2016.

Liquidity and Capital Resources
(in thousands, except per share data)

We incurred net losses of $30.8 million, $71.9 million, and $103.0 million for the years ended December 31, 2018, 2017, and
2016, respectively. Net cash used in operating activities was $25.2 million, $71.3 million, and $91.6 million for those same periods. At
December 31, 2018, we had an accumulated deficit of $388.3 million, working capital of $44.6 million, cash and cash equivalents of
$32.9 million, and marketable securities of $28.6 million.

Net cash used in operating activities was $25.4 million for the year ended December 31, 2018 and consisted primarily of a net loss

of $30.8 million. Cash outflows were partially offset by non-cash expenses for stock compensation of $4.4 million and other non-cash
adjustments.

Net cash used in operating activities was $71.3 million for the year ended December 31, 2017 and consisted primarily of a net loss

of $71.9 million. Cash outflows were partially offset by non-cash expense for stock compensation of $6.4 million, a decrease in accounts
payable and accrued expenses of $8.4 million primarily associated with the completion of the Phase 3 oliceridine clinical trials, and other
non-cash adjustments.

Net cash used in operating activities was $91.6 million for the year ended December 31, 2016 and consisted primarily of a net loss

of $103.0 million and net cash outflows from a decrease in deferred revenue of $3.8 million. These cash outflows were partially offset by
non-cash expense for stock compensation of $5.9 million, an increase in accounts payable and accrued.

Net cash provided by (used in) investing activities

Net cash provided by investing activities was $21.0 million for the year ended December 31, 2018. Investing activities consisted

primarily of purchases and maturities of marketable securities.

Table of Contents

Net cash provided by investing activities for the years ended December 31, 2017 and 2016 was $32.8 million and $37.8 million,

respectively, and was primarily from the maturities of marketable securities. 2017 also included expenditures related to the July 2017
relocation of our corporate headquarters to Chesterbrook, Pennsylvania.

Net cash provided by financing activities

Net cash provided by financing activities was $20.6 million for the year ended December 31, 2018, which was primarily due to net

proceeds of $33.2 million from the sale of common stock through our at-the-market, or ATM, sales facility, offset by principal repayments
on our Term Loans of $12.7 million.

Net cash provided by financing activities was $31.0 million for the year ended December 31, 2017, which was primarily due to net
proceeds of $20.7 million from the sale of common stock through our ATM sales facilities, and net proceeds of $9.9 million from the March
31, 2017 draw of Term Loan C.

Net cash provided by financing activities was $32.3 million for the year ended December 31, 2016, which was primarily due to net

proceeds of $32.1 million from the sale of common stock in February and December 2016 pursuant to our ATM sales facility.

All periods presented also include proceeds from exercises of common stock options.

Operating and Capital Expenditure Requirements

We have not achieved profitability since our inception and we expect to continue to incur net losses and negative cash flows from

operations for the foreseeable future. We expect our cash expenditures to continue to be significant in the near term as we seek to address the
items in the oliceridine CRL, including conducting an additional clinical study, continue clinical development of TRV250, and began IND-
enabling work for TRV045. Over the next twelve months, we anticipate that our total operating expenses will be comparable to the previous
twelve months.

We believe that our cash and cash equivalents and marketable securities as of December 31, 2018, together with interest thereon,

and the approximately $9.2 million of net proceeds received in the first quarter of 2019 from our sale of common stock in a registered direct
offering, to be sufficient to fund our operating expenses and capital expenditure requirements into the third quarter of 2020. Our anticipated
operating expenses involve significant risks and uncertainties and are dependent on our current assessment of the extent and costs of
activities required to address the comments in the oliceridine CRL. However, at this time, we have not yet received feedback from the FDA
on the draft protocol and analysis plan we have submitted and we have not commenced the additional activities that we believe will be
required for us to resubmit the oliceridine NDA. As such, our assessment of these costs and activities may change in the future. In the
future, we anticipate that we will need to raise substantial additional financing to fund our operations. To meet these requirements, we may
seek to sell equity or convertible securities in public or private transactions that may result in significant dilution to our stockholders,
however, at this time we are not permitted to sell equity securities until April 1, 2019, as a result of our registered direct offering. In June
2018, we filed a $175.0 million shelf registration statement that includes a $50.0 million ATM sales facility, of which there was
approximately $36.4 million of available capacity as of December 31, 2018. We may offer and sell shares of our common stock under the
existing registration statement or any registration statement we may file in the future. If we raise additional funds through the issuance of
convertible securities, these securities could have rights senior to those of our common stock and could contain covenants that restrict our
operations.

Ultimately, there can be no assurance that we will be able to obtain additional equity or debt financing on terms acceptable to us, if

at all. Our future capital requirements will depend on many factors, including:

·

·

the scope, progress, results and costs of researching and developing our product candidates, including oliceridine, or any future
product candidates, both in the United States and in territories outside the United States;

the number and development requirements of any other product candidates that we may pursue;

·

·

·

·

·

·

our ability to enter into collaborative agreements for the development and/or commercialization of our product candidates,
including for oliceridine;

the costs, timing, and outcome of any regulatory review of oliceridine and any future product candidates, both in the United States
and in territories outside the United States;

the costs, timing, and extent of future commercialization activities, including product manufacturing, marketing, sales and
distribution, for any of our product candidates for which we receive marketing approval;

the revenue, if any, received from commercial sales of our product candidates for which we receive marketing approval;

any product liability or other lawsuits, including the recently filed class action and stockholder derivative complaints, related to
our products or our Company;

the expenses needed to attract and retain skilled personnel; and

the costs involved in preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property
rights and defending our intellectual property-related claims, both in the United States and in territories outside the United States.

Please see “Risk Factors” for additional risks associated with our substantial capital requirements.

Chesterbrook, Pennsylvania. Future rent streams of $1.1 million to be collected in less than one year and $2.0 million to be
collected between one and three years are not offset against operating lease obligations.

Other Commitments

In the course of normal business operations, we have agreements with contract service providers to assist in the performance of our

research and development and manufacturing activities. We can elect to discontinue the work under these agreements at any time. We also
could enter into additional collaborative research, contract research, manufacturing and supplier agreements in the future, which may require
upfront payments and even long-term commitments of cash.

We have no material non‑cancelable purchase commitments with contract manufacturers or service providers as we have generally
contracted on a cancelable basis. In December 2016 and October 2017, we entered into manufacturing agreements that are cancelable upon
24 months prior notice of cancellation.

REPORT OF MANAGEMENT

Management’s Report on Financial Statements

Our management is responsible for the preparation, integrity and fair presentation of information in our financial statements,

including estimates and judgments. The financial statements presented in this Annual Report on Form 10‑K have been prepared in
accordance with accounting principles generally accepted in the United States of America. Our management believes the financial
statements and other financial information included in this Annual Report on Form 10‑K fairly present, in all material respects, our financial
condition, results of operations and cash flows as of and for the periods presented in this Annual Report on Form 10‑K. The financial
statements have been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report, which is
included herein.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal
control system was designed to provide reasonable assurance to our management and board of directors regarding the preparation and fair
presentation of published financial statements. Internal control over financial reporting is defined in Rule 13a‑15(f) or
15d‑15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, our principal executive and principal
financial officers and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted
accounting principles and includes those policies and procedures that:

·

·

·

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect our transactions and dispositions of
our assets;

provide reasonable assurance that our transactions are recorded as necessary to permit preparation of our financial statements in
accordance with accounting principles generally accepted in the United States of America, and that our receipts and expenditures
are being made only in accordance with authorization of our management and our directors; and

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our
assets that could have a material effect on our financial statements.

Our management, including our Chief Executive Officer and Vice President, Finance, do not expect that our internal control over
financial reporting will prevent all error and all fraud. A control system, no matter how well designed and implemented, can provide only
reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a control system must reflect the
fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent
limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues within a company are
detected. The inherent limitations include the realities that judgments in decision‑making can be faulty, and that breakdowns can occur
because of simple errors or mistakes. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more
people or by management override of the controls. Because of the inherent limitations in a cost‑effective control system, misstatements due
to error or fraud may occur and may not be detected.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2018. In making
this assessment, our management used the criteria based on the framework set forth by the Committee of Sponsoring Organizations of the
Treadway Commission in “Internal Control—Integrated Framework” (COSO). Based on our assessments we believe that, as of
December 31, 2018, our internal control over financial reporting is effective based on those criteria.

Report of Independent Registered Public Accounting Firm 

To the Shareholders and the Board of Directors of Trevena, Inc.

Opinion on the Financial Statements

We have audited the accompanying balance sheets of Trevena, Inc. (the “Company“) as of December 31, 2018 and 2017, the related
statements of income and comprehensive loss, stockholders’ equity, and cash flows, for each of the three years in the period ended
December 31, 2018, and the related notes (collectively referred to as the “financial statements“). In our opinion, the financial statements
present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017, and the results of its
operations and its cash flows for each of the three years in the period ended December 31, 2018, in conformity with US generally accepted
accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on
the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting
Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S.
federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The
Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our
audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an
opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or
fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the
amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant
estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide
a reasonable basis for our opinion.

We have served as the Company’s auditor since 2007.

Notes to Financial Statements 

December 31, 2018

1. Organization and Description of the Business

Trevena, Inc., or the Company, was incorporated in Delaware as Parallax Therapeutics, Inc. on November 9, 2007. The Company
began operations in December 2007, and its name was changed to Trevena, Inc. on January 3, 2008. The Company is a biopharmaceutical
company focused on the development and commercialization of innovative treatment options that target and treat diseases affecting the
central nervous system, or CNS. The Company operates in one segment and has its principal office in Chesterbrook, Pennsylvania.

Since commencing operations in 2007, the Company has devoted substantially all of its financial resources and efforts to research

and development, including preclinical studies and clinical trials. The Company has never been profitable and has not yet commenced
commercial operations. On November 2, 2018, the U.S. Food and Drug Administration, or FDA, issued a complete response letter, or CRL,
with respect to the Company’s new drug application, or NDA, for oliceridine. In the CRL, the FDA requested additional clinical data on the
QT interval and indicated that the submitted safety database was not of adequate size for the proposed labeling. The FDA also requested
certain additional nonclinical data and validation reports. On January 28, 2019, the Company announced the receipt of the official Type A
meeting minutes from the FDA regarding the CRL wherein it agreed that the current oliceridine safety database will support labeling at a
maximum daily dose of 27 mg. The FDA also agreed that the Company can conduct a study in healthy volunteers to collect the requested
QT interval data and that the study should include placebo- and positive-control arms. The Company has submitted a detailed protocol and
analysis plan to the FDA and, following receipt of FDA feedback, anticipates initiating the study in the first half of 2019.  To address
remaining items in the CRL, the FDA indicated that the Company should include supporting nonclinical data related to the characterization
of the 9662 metabolite and the remaining product validation reports when the Company resubmits the oliceridine NDA.

On November 8, 2018, the Company announced a restructuring of its workforce. See Note 10 for additional information.

Since the Company’s inception, the Company has incurred losses and negative cash flows from operations. At December 31, 2018,

the Company had an accumulated deficit of $388.3 million. The Company’s net loss was $30.8 million, $71.9 million and $103.0 million
for the years ended December 31, 2018, 2017 and 2016, respectively. The Company expects its cash and cash equivalents of $32.9 million
and marketable securities of $28.6 million as of December 31, 2018, together with interest thereon, to be sufficient to fund its operating
expenses and capital expenditure requirements into the third quarter of 2020.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statements have been prepared in conformity with accounting principles generally accepted in the

United States of America, or U.S. GAAP. Any reference in these notes to applicable guidance is meant to refer to the authoritative United
States generally accepted accounting principles as found in the Accounting Standards Codification, or ASC, and Accounting Standards
Update, or ASU, of the Financial Accounting Standards Board, or FASB. The Company’s functional currency is the U.S. dollar.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumption

that affect the amounts reported in the financial statements and accompanying notes. Management used significant estimates in the
following areas, among others: stock-based compensation expense, the determination of the

83

 
 
Table of Contents

fair value of stock-based awards, the fair value of liability-classified common stock warrants, the accounting for research and development
costs, accrued expenses and the recoverability of the Company’s net deferred tax assets and related valuation allowance. The financial data
and other information disclosed in these notes are not necessarily indicative of the results to be expected for any future year or period. The
Company bases its estimates on historical experience and also on assumptions that it believes are reasonable, however, actual results could
significantly differ from those results.

Cash and Cash Equivalents and Marketable Securities

The Company considers all highly liquid investments that have maturities of three months or less when acquired to be cash

equivalents. Cash equivalents are valued at cost, which approximates their fair market value. The Company maintains a portion of its cash
and cash equivalent balances in money market mutual funds that may invest substantially all of their assets in U.S. government agency
securities and U.S. Treasury securities.

The Company classifies its marketable securities as “available-for-sale”, pursuant to ASC Topic 320, Investments—Debt and

Equity Securities, or ASC 320, carries them at fair market value and classifies them as current assets on its balance sheets. Unrealized gains
and losses on marketable securities are recorded as a separate component of accumulated other comprehensive income/(loss) included in
stockholders’ equity. As of December 31, 2018 and 2017, the Company had $28.6 million and $49.5 million, respectively, in available-for-
sale investments, all classified as current assets. See Note 3 for additional information.

The fair value of the Company’s investments is determined based on observable market quotes or valuation models using
assessments of counterparty credit worthiness, credit default risk of underlying security and overall capital market liquidity. The Company
reviews unrealized losses associated with available-for-sale securities to determine the classification as “temporary” or “other-than-
temporary” impairment. A temporary impairment results in an unrealized loss being recorded in other comprehensive income (loss). If a
decline in the fair value is considered other-than-temporary, based on available evidence, the unrealized loss is transferred from other
comprehensive income (loss) to the statement of operations. The Company considers various factors in determining the classification,
including the length of time and extent to which the fair value has been less than the Company’s cost basis, the financial condition and near-
term prospects of the issuer or investee, and the Company’s ability to hold the investment for a period of time sufficient to allow for any
anticipated recovery in market value. Realized gains (losses) are included in interest income (expense) in the statement of operations and
comprehensive income (loss) on a specific identification basis.

Restricted Cash

The Company maintains $1.3 million as collateral under a letter of credit for the Company’s facility lease obligations in

Chesterbrook, Pennsylvania. The Company has recorded this deposit and accumulated interest thereon as restricted cash on its balance
sheet.

Fair Value of Financial Instruments

The carrying amount of the Company’s financial instruments, which include cash and cash equivalents, marketable securities,

restricted cash, accounts payable and accrued expenses approximate their fair values, given their short-term nature. The carrying amount of
the Company’s loans payable at December 31, 2018 and 2017 is the nominal value of the loan payable, net of debt discount and deferred
charges. The nominal value approximates fair value because the interest rate is reflective of the rate the Company could obtain on debt with
similar terms and conditions. Certain of the Company’s common stock warrants are carried at fair value, as disclosed in Note 3.

The Company has evaluated the estimated fair value of financial instruments using available market information and
management’s estimates. The use of different market assumptions and/or estimation methodologies could have a significant effect on the
estimated fair value amounts. See Note 3 for additional information.

84

 
Table of Contents

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk are primarily cash, cash equivalents,

marketable securities and restricted cash. The Company’s investment policy includes guidelines on the quality of the institutions and
financial instruments and defines allowable investments that the Company believes minimizes the exposure to concentration of credit risk.
The Company has no off-balance sheet concentrations of credit risk such as foreign currency exchange contracts, option contracts or other
hedging arrangements.

Property and Equipment

Property and equipment consists of computer and laboratory equipment, software, office equipment, furniture, manufacturing
equipment and leasehold improvements and is recorded at cost. Maintenance and repairs that do not improve or extend the lives of the
respective assets are expensed to operations as incurred. Upon disposal, retirement or sale, the related cost and accumulated depreciation is
removed from the accounts and any resulting gain or loss is included in the results of operations. Property and equipment are depreciated on
a straight‑line basis over their estimated useful lives. The Company uses a life of three years for computer equipment and five years for
laboratory equipment, office equipment, furniture, manufacturing equipment and software. Leasehold improvements are amortized over the
shorter of the lease term or the estimated useful life of the asset.

The Company reviews long‑lived assets when events or changes in circumstances indicate the carrying value of the assets may not

be recoverable. Recoverability is measured by comparison of the book values of the assets to future net undiscounted cash flows that the
assets are expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by
which the book value of the assets exceed their fair value, which is measured based on the projected discounted future net cash flows arising
from the assets. No impairment losses have been recorded since inception.

Intangible Asset

The intangible asset recorded in the Company’s financial statements was associated with the acquisition of the domain name for the

Company’s website. Identifiable intangible assets are initially recorded at fair market value at the time of acquisition, utilizing a cost
approach and the initial value is amortized over the expected useful life of the asset. The Company also capitalizes costs incurred to renew
or extend the term of recognized intangible assets.

Common Stock Warrants

Freestanding warrants that are related to the purchase of common stock are classified as liabilities and recorded at fair value

regardless of the timing of the redemption feature or the redemption price or the likelihood of redemption. These warrants are subject to re-
measurement at each balance sheet date and any change in fair value is recognized as a component of change in fair value of warrant
liability in the statements of operations and comprehensive loss. The Company will continue to adjust the liability for changes in fair value
until the earlier of the exercise or expiration of the warrants. The warrants are classified as Level 3 liabilities. The value of these warrants
was immaterial as of December 31, 2018 and 2017.

In addition, in connection with entering into loan agreements, the Company has issued warrants to purchase shares of the
Company’s common stock. These detachable warrant instruments qualify for equity classification and have been allocated upon the relative
fair value of the base instrument and the warrant. See Note 6 for additional information.

Segment Information

Operating segments are identified as components of an enterprise about which separate discrete financial information is available

for evaluation by the chief operating decision maker, or decision-making group, in making decisions on how to allocate resources and assess
performance. The Company’s chief operating decision maker is the chief executive officer. The Company and the chief executive officer
view the Company’s operations and manage its business as one operating segment. All long-lived assets of the Company reside in the
United States.

Table of Contents

Revenue

ASC 605 Revenue

Prior to the adoption of FASB’S ASC 606, the Company recognized revenue under FASB’s ASC 605. Under ASC 605, the

Company recognized collaboration revenue when persuasive evidence of an arrangement existed, delivery had occurred or services had
been rendered, the price was fixed and determinable, and collectability was reasonably assured.

ASC 606 Revenue

In accordance with FASB’s ASC 606, Revenue from Contracts with Customers, or ASC 606, the Company recognizes revenue
when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to
receive in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within
the scope of ASC 606, it performs the following five steps:

(i) 

(ii)

(iii)

(iv)

(v)

identify the contract(s) with a customer;

identify the performance obligations in the contract;

determine the transaction price;

allocate the transaction price to the performance obligations in the contract; and

recognize revenue when (or as) the entity satisfies a performance obligation.

The Company applies the five-step model to contracts when it determines that it is probable it will collect the consideration it is

entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be
within the scope of ASC 606, the Company assesses the goods or services promised within each contract and determines those that are
performance obligations, and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the
amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is
satisfied.

Amounts received prior to satisfying the revenue recognition criteria are recognized as deferred revenue in the Company’s balance

sheet. Amounts expected to be recognized as revenue within the twelve months following the balance sheet date are classified as Current
portion of deferred revenue. Amounts not expected to be recognized as revenue within the twelve months following the balance sheet date
are classified as Deferred revenue, net of current portion. As of December 31, 2018 and 2017, the Company did not have a deferred revenue
balance.

License Revenues

The Company’s revenues have primarily been generated through licensing arrangements. The terms of these agreements typically

include payment to the Company of one or more of the following: nonrefundable, up-front license fees; regulatory and commercial
milestone payments; payments for manufacturing supply services; and royalties on net sales of licensed products.

In determining the appropriate amount of revenue to be recognized as it fulfills its obligations under each of its agreements, the

Company performs the following steps:

(i)

(ii)

identification of the promised goods or services in the contract;

determination of whether the promised goods or services are performance obligations including whether they
are distinct in the context of the contract;

86

 
Table of Contents

(iii)

measurement of the transaction price, including the constraint on variable consideration;

(iv)

allocation of the transaction price to the performance obligations; and

(v)

recognition of revenue when (or as) the Company satisfies each performance obligation.

See Note 8 for additional details surrounding the Company’s licensing arrangements.

The Company also assesses whether there is an option in a contract to acquire additional goods or services. An option gives rise to

a performance obligation only if the option provides a material right to the customer that it would not receive without entering into that
contract. Factors that the Company considers in evaluating whether an option represents a material right include, but are not limited to: (i)
the overall objective of the arrangement, (ii) the benefit the collaborator might obtain from the arrangement without exercising the option,
(iii) the cost to exercise the option (e.g. priced at a significant and incremental discount) and (iv) the likelihood that the option will be
exercised. With respect to options determined to be performance obligations, the Company recognizes revenue when those future goods or
services are transferred or when the options expire.

The Company’s revenue arrangements may include the following:

Up-front License Fees: If a license is determined to be distinct from the other performance obligations identified in the

arrangement, the Company recognizes revenues from nonrefundable, up-front fees allocated to the license when the license is transferred to
the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other promises, the Company
utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is
satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue
from non-refundable, up-front fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the
measure of performance and related revenue recognition.

Milestone Payments: At the inception of an agreement that includes regulatory or commercial milestone payments, the Company
evaluates whether each milestone is considered probable of being achieved and estimates the amount to be included in the transaction price
using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is
included in the transaction price. Milestone payments that are not within the control of the Company or the licensee, such as regulatory
approvals, are not considered probable of being achieved until those approvals are received. At each reporting period, the Company
assesses the probability of achievement of each milestone under its current agreements.

Research and Development Activities:  Under the Company’s current collaboration and license arrangements, if the Company is

entitled to reimbursement for costs for services provided by the Company, it expects such reimbursement would be an offset to research and
development expenses.

Royalties: If the Company is entitled to receive sales-based royalties from its collaborator, including milestone payments based on
the level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company recognizes revenue at the
later of (i) when the related sales occur, provided the reported sales are reliably measurable, or (ii) when the performance obligation to
which some or all of the royalty has been allocated has been satisfied (or partially satisfied).

Manufacturing Supply and Research Services: Arrangements that include a promise for future supply of drug substance or drug

product for either clinical development or commercial supply at the licensee’s discretion are generally considered as options. The Company
assesses if these options provide a material right to the licensee and if so, they are accounted for as separate performance obligations.

The Company receives payments from its licensees based on schedules established in each contract. Upfront payments are
recorded as deferred revenue upon receipt, and may require deferral of revenue recognition to a future period until the Company performs its
obligations under these arrangements. Amounts are recorded as accounts

87

 
Table of Contents

receivable when the Company’s right to consideration is unconditional. The Company does not assess whether a contract has a significant
financing component if the expectation at contract inception is such that the period between payment by the licensees and the transfer of the
promised goods or services to the licensees will be one year or less.

Research and Development

Research and development costs are charged to expense as incurred. Research and development costs include, but are not limited
to, personnel expenses, clinical trial supplies, fees for clinical trial services, manufacturing costs, consulting costs, and allocated overhead,
including rent, equipment, depreciation, and utilities.

Costs for certain development activities, such as clinical trials, are recognized based on an evaluation of the progress to completion
of specific tasks using data such as subject enrollment, clinical site activations or information provided to the Company by its vendors with
respect to their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ
from the pattern of costs incurred, and are reflected in the financial statements as prepaid or accrued research and development expense, as
the case may be.

As part of the process of preparing its financial statements, the Company is required to estimate its expenses resulting from its

obligations under contracts with vendors, clinical research organizations and consultants, and under clinical site agreements in connection
with conducting clinical trials. The financial terms of these contracts are subject to negotiations, which vary from contract to contract and
may result in payment flows that do not match the periods over which materials or services are provided under such contracts. The
Company’s objective is to reflect the appropriate trial expenses in its financial statements by matching those expenses with the period in
which services are performed and efforts are expended. The Company may account for these expenses according to the progress of the trial
as measured by subject progression and the timing of various aspects of the trial. The Company determines accrual estimates through
financial models taking into account discussion with applicable personnel and outside service providers as to the progress or state of
consummation of trials, or the services completed. During the course of a clinical trial, the Company adjusts its clinical expense recognition
if actual results differ from its estimates. The Company makes estimates of its accrued expenses as of each balance sheet date based on the
facts and circumstances known to it at that time. The Company’s clinical trial accruals are dependent upon the timely and accurate reporting
of contract research organizations and other third-party vendors. Although the Company does not expect its estimates to be materially
different from amounts actually incurred, its understanding of the status and timing of services performed relative to the actual status and
timing of services performed may vary and may result in it reporting amounts that are too high or too low for any particular period. For
the years ended December 31, 2018, 2017, and 2016, there were no material adjustments to the Company’s prior period estimates of
accrued expenses for clinical trials.

Stock‑Based Compensation

At December 31, 2018, the Company had two stock‑based compensation plans, which are more fully described in Note 7. The
Company has applied the fair value recognition provisions of Financial Accounting Standards Board Accounting Standards Codification
Topic 718, Compensation — Stock Compensation, to account for stock-based compensation for employees. The Company recognizes
compensation costs related to stock options granted to employees based on the estimated fair value of the awards on the date of grant.

The Company has equity incentive plans under which various types of equity-based awards including, but not limited to, incentive

stock options, non-qualified stock options, and restricted stock awards, may be granted to employees, non-employee directors, and non-
employee consultants. The Company also has an inducement plan under which various types of equity-based awards, including non-
qualified stock options and restricted stock awards, may be granted to new employees.

For stock options granted to employees and directors, the Company recognizes compensation expense for all stock-based awards

based on the estimated grant-date fair values. For restricted stock awards to employees, the fair value is based on the closing price of the
Company’s common stock on the date of grant. The value of the portion of the award that is ultimately expected to vest is recognized as
expense ratably over the requisite service period. The fair value of stock options is determined using the Black-Scholes option pricing
model. The Company utilizes a dividend yield of

88

 
Table of Contents

zero based on the fact that the Company has never paid cash dividends and has no current intention of paying cash dividends. As of
fiscal year ended December 31, 2016, the Company adopted the forfeiture rate methodology change in accordance with ASU 2016‑09 to
record forfeitures as they occur.

Stock-based compensation expense related to restricted stock units granted to employees is recognized based on the grant-date fair

value of each award and recorded as expense over the vesting period using the straight-line method. Forfeitures are recorded as they occur.

See Note 7 for a discussion of the assumptions used by the Company in determining the grant date fair value of options granted under
the Black‑Scholes option pricing model, as well as a summary of the stock option activity under the Company’s stock‑based compensation
plan for all years presented.

Income Taxes

Income taxes are recorded in accordance with ASC Topic 740, Income Taxes, or ASC 740, which provides for deferred taxes using

an asset and liability approach. The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of
events that have been included in the financial statements or tax returns. Deferred tax assets and liabilities are determined based on the
difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the
differences are expected to reverse. Valuation allowances are provided, if based upon the weight of available evidence, it is more likely than
not that some or all of the deferred tax assets will not be realized.

The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740. When uncertain tax positions

exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit will more likely than not be realized. The
determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position, as
well as consideration of the available facts and circumstances. To date, the Company has not taken any uncertain tax position or recorded
any reserves, interest or penalties.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs
Act, or the Tax Act. Additionally, the SEC staff issued SAB 118, which provides guidance on accounting for the effects of the Tax Act. See
Note 13.

Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions and

other events and circumstances from non-owner sources. Comprehensive income (loss) relates to unrealized investment gains or losses on
the Company’s marketable securities for all periods presented.

Basic and Diluted Net Loss Per Share of Common Stock

The Company’s basic net loss per share is calculated by dividing the net loss by the weighted average number of shares of

common stock outstanding for the period. The diluted net loss per common share is computed by giving effect to all potential dilutive
common stock equivalents outstanding for the period. Because the impact of these items is anti‑dilutive during periods of net loss, there was
no difference between basic and diluted net loss per share of common stock for all periods presented.

 Recently Adopted Accounting Standards

In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118, or SAB 118, which provides guidance on accounting

for the tax effects of the TCJA. SAB 118 was issued to address the application of GAAP in situations when a registrant does not have the
necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain
income tax effects of the Act and allows the Company to record provisional amounts during a measurement period not to extend beyond one
year of the TCJA enactment date. The Company has completed its analysis of the impacts of the TCJA, including analyzing the effects of

89

 
 
Table of Contents

any Internal Revenue Service (IRS) and U.S. Treasury guidance issued, and state tax law changes enacted, within the maximum one year
measurement period resulting in no significant adjustments to the provisional amount previously recorded.

In May 2017, the FASB issued ASU 2017-09, Stock Compensation - Scope of Modification Accounting, which amends the scope

of modification accounting for share-based payment arrangements. The amendment provides guidance about which changes to the terms or
conditions of a share-based payment award require an entity to apply modification accounting. The new standard is effective for fiscal years
beginning after December 15, 2017. The adoption of this standard did not have an impact on the Company’s consolidated financial
statements.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), to clarify how certain cash receipts and
payments should be presented in the statement of cash flows. The standard is effective for annual periods beginning after December 15,
2017 and interim periods within that reporting period. The adoption of this standard did not have an impact on the Company’s consolidated
financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 is a comprehensive new

revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer in an amount
reflecting the consideration it expects to receive in exchange for those goods or services. Additionally, in March 2016, the FASB issued
ASU 2016-08, Revenue from Contracts with Customers, Principal versus Agent Considerations. ASU 2016-08 amends the principal versus
agent guidance in ASU 2014-09 to clarify how an entity should identify the unit of accounting for the principal versus agent evaluation and
how it should apply the control principal to certain types of arrangements. The effective date for both standards is January 1, 2018. The
Company adopted these standards on January 1, 2018 and elected the modified retrospective transition method, meaning the cumulative
effect of applying the new guidance, if any, was recognized at that date as an adjustment to the opening accumulated deficit balance. There
was no impact to the Company’s financial statements upon adoption, as the Company did not have any contracts with customers as of the
adoption date.

Recent Accounting Standards Not Yet Adopted

 In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other
Comprehensive Income, which provides the option to reclassify stranded tax effects within accumulated other comprehensive income to
retained earnings. This option would be available in each period in which the effect of the change in the U.S. federal corporate income tax
rate in the Tax Act (or a portion thereof) is recorded. This is effective for the Company beginning after December 15, 2018, with early
adoption permitted. These amendments should be applied in the period of adoption or retrospectively to each period in which the effect of
the change in the U.S federal corporate income tax rate in the Tax Act is recognized. The Company is evaluating the effect this standard will
have on its financial statements and related disclosures. See Note 13.

In February 2016, the FASB issued ASU 2016‑02, Leases (Topic 842), which requires lessees to record most leases on their

balance sheets and disclose key information about leasing arrangements in an effort to increase transparency and comparability among
organizations. The standard is effective for annual periods beginning after December 15, 2018 and interim periods within that reporting
period. The Company will adopt the standard on January 1, 2019 and is finalizing its evaluation of the effect this standard will have on its
financial statements and related disclosures related to its existing operating leases. The Company will recognize a right of use asset and
corresponding lease liability related to its operating leases as of the date of adoption. The Company will elect to apply the package of
practical expedients which allows entities not to reassess whether contracts are or contain leases, lease classification, and whether initial
direct costs qualify for capitalization. The Company will elect not to separate lease and non-lease components and will not apply the
hindsight practical expedient. The adoption of this guidance will have a material effect on the Company’s balance sheet and disclosures. The
Company is also finalizing its process and internal controls required to comply with the new lease accounting and disclosure requirements
set by the new standard on an ongoing basis.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the

Disclosure Requirements for Fair Value Measurement. The new guidance modifies the disclosure

90

 
Table of Contents

requirements related to fair value measurements in Topic 820, Fair Value Measurement, including removing certain previous disclosure
requirements, adding certain new disclosure requirements, and modifying certain other disclosure requirements. The ASU will be effective
for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. The
Company is evaluating the effect this standard will have on its financial statements and related disclosures.

3. Fair Value of Financial Instruments

ASC Topic 820, Fair Value Measurement, or ASC 820, establishes a fair value hierarchy for instruments measured at fair value

that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable
inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from
sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market
participants would use in pricing the asset or liability, and are developed based on the best information available in the circumstances.

ASC 820 identifies fair value as the exchange price, or exit price, representing the amount that would be received to sell an asset or
paid to transfer a liability in an orderly transaction between market participants. As a basis for considering market participant assumptions in
fair value measurements, ASC 820 establishes a three-tier fair value hierarchy that distinguishes among the following:

Level 1—Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the
ability to access.

Level 2—Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar
assets or liabilities in markets that are not active and models for which all significant inputs are observable, either directly or
indirectly.

Level 3—Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the
determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair
value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest
level of any input that is significant to the fair value measurement.

(1) The fair value of Level 1 securities is estimated based on quoted prices in active markets for identical assets or liabilities.

(2) The fair value of Level 2 securities is estimated based on observable inputs other than quoted prices in active markets for identical

assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable
or can be corroborated by observable market data for substantially the full term on the assets or liabilities.

The Company classifies investments available to fund current operations as current assets on its balance sheets. As of

December 31, 2018, the Company did not hold any investment securities exceeding a one-year maturity.

Unrealized gains and losses on marketable securities are recorded as a separate component of accumulated other comprehensive

income (loss) included in stockholders’ equity. Realized gains (losses) are included in interest income (expense) in the statement of
operations and comprehensive income (loss) on a specific identification basis. The Company did not record any realized gains or losses
during the years ended December 31, 2018 and 2017. To date, the Company has not recorded any impairment charges on marketable
securities related to other-than-temporary declines in market value.

The Company recognizes transfers between levels of the fair value hierarchy as of the end of the reporting period. We do not hold
material Level 3 securities, and therefore, there were no transfers in or out of Level 3 in the hierarchy during the years ended December 31,
2018 or 2017.

In September 2014, the Company entered into a loan and security agreement with Oxford Finance LLC and Pacific Western Bank

(formerly Square 1Bank) (together, the lenders), pursuant to which the lenders agreed to lend the Company up to $35.0 million in a three-
tranche series of term loans (Term Loans A, B, and C). Upon initially entering into the agreement, the Company borrowed $2.0 million
under Term Loan A. In April 2015, the Company amended the agreement with the lenders to change the draw period for Term Loan B. In
December 2015, the Company further amended the agreement with the lenders to, among other things, change the draw period for Term
Loan C, modify the interest only period, and modify the maturity date of the loan. In December 2015, the Company borrowed the Term
Loan B tranche of $16.5 million. The Company’s ability to draw an additional $16.5 million under Term Loan C was subject to the
satisfaction of one or more specified triggers related to the results of the Company’s Phase 2b clinical trial of TRV027, which were
announced in May 2016. Although those triggers were not attained, in December 2016, the Company and the lenders modified the terms and
conditions under which the Company could exercise an option to draw $10.0 million of Term Loan C. In March 2017, the Company
borrowed the Term Loan C tranche of $10.0 million.

Borrowings under Term Loans A and B accrue interest at a fixed rate of 6.50% per annum. Borrowings under Term Loan C accrue

interest at a fixed rate of 6.98% per annum. The Company was required to make payments of interest only on borrowings under the loan
agreement on a monthly basis through and including January 1, 2018. Payments of principal in equal monthly installments and accrued
interest began on January 1, 2018 and will continue to be due until the loan matures on March 1, 2020. As of December 31, 2018, there was
$15.8 million aggregate principal balance outstanding under the terms loans. Upon the last payment date of the amounts borrowed under the
agreement, the Company will be required to pay a final payment fee equal to 6.6% of the aggregate amounts borrowed, which is recorded as
interest expense over the term of the loans payable. In addition, if the Company repays Term Loan A, Term Loan B, or Term Loan C prior
to the applicable maturity date, it will pay the lenders a prepayment fee of 1.0% of each of Term Loans A and B, and 2.0% of Term Loan C,
if the prepayment occurs on or between April 1, 2018 and March 31, 2019, and 1.0% of Term Loan C, if the prepayment occurs on or after
April 1, 2019.

The Company’s obligations under the loan and security agreement are secured by a first priority security interest in substantially all

of the assets of the Company, including the Company’s cash, cash equivalents, and marketable securities but excluding the Company’s
intellectual property (together, the collateral). The Company has agreed not to pledge or otherwise encumber its intellectual property, other
than through grants of certain permitted non-exclusive or exclusive licenses or other conveyances of its intellectual property.

The loan and security agreement includes affirmative and restrictive covenants, including: (a) financial reporting requirements;
(b) limitations on the incurrence of indebtedness; (c) limitations on liens; (d) limitations on certain merger and acquisition transactions;
(e) limitations on dispositions of certain assets; (f) limitations on fundamental corporate changes (including changes in control);
(g) limitations on investments; (h) limitations on payments and distributions and (i) other covenants. The agreement also contains certain
events of default, including for payment defaults, breaches of covenants, a material adverse change in the Company’s business, operations
or condition (financial or otherwise), a material impairment in the value of the collateral or in the prospect of repayment of the Company’s
obligations to the lender, certain levies, attachments and other restraints on the Company’s business,

93

 
 
 
    
    
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

insolvency, defaults under other agreements and misrepresentations. Upon an event of default, the lenders have the right to foreclose upon
the available collateral, including the Company’s existing cash and cash equivalents and marketable securities.

In connection with entering into the agreement, the Company issued to the lenders and the placement agent warrants to purchase an
aggregate of 7,678 shares of Trevena common stock, of which 5,728 shares remain outstanding as of December 31, 2018. These detachable
warrant instruments have qualified for equity classification and have been allocated upon the relative fair value of the base instrument and
the warrants, according to the guidance of ASC 470‑20‑25‑2. These warrants are exercisable immediately and have an exercise price of
$5.8610 per share. The warrants may be exercised on a cashless basis and will terminate on the earlier of September 19, 2024 or the closing
of a merger or consolidation transaction in which the Company is not the surviving entity. In connection with the draw of Term Loan B, the
Company issued to the lenders and the placement agent additional warrants to purchase an aggregate of 34,961 shares of Trevena common
stock. These warrants have substantially the same terms as those noted above, have an exercise price of $10.6190 per share and an
expiration date of December 23, 2025. In connection with draw of Term Loan C, the Company issued to the lenders and placement agent
additional warrants to purchase an aggregate of 62,241 shares of its common stock. These warrants have substantially the same terms as
those noted above, and have an exercise price of $3.6150 per share and an expiration date of March 31, 2027.

As of December 31, 2018, borrowings of $15.8 million attributable to Term Loans A, B and C are outstanding. Interest expense of

$1.4 million, $1.7 million and $1.2 million was recorded during the years ended December 31, 2018, 2017 and 2016, respectively. The
Company incurred lender and third-party costs of $1.0 million, related to the issuance of its term loans. Per ASU 2015‑03, Interest-
Imputation of Interest, debt discount and debt issuance costs are to be presented as a contra-liability to the debt on the balance sheet. These
costs will be amortized to interest expense over the life of the loans using the effective interest method. A total of $0.2 million, $0.3 million
and $0.1 million of debt discount and debt issuance costs were amortized to interest expense during the years ended December 31, 2018,
2017, and 2016, respectively.

7. Stockholders’ Equity

Equity Offerings

Under its certificate of incorporation, the Company was authorized to issue up to 200,000,000 and 100,000,000 shares of common
stock as of December 31, 2018 and December 31, 2017, respectively. The Company also was authorized to issue up to 5,000,000 shares of
preferred stock as of each of December 31, 2018 and December 31, 2017. The Company is required, at all times, to reserve and keep
available out of its authorized but unissued shares of common stock sufficient shares to effect the conversion of the shares of the preferred
stock and all outstanding stock options and warrants.

On December 14, 2015, the Company entered into an at the market, or ATM, sales agreement, or the Prior ATM Agreement, with

Cowen and Company, LLC, or Cowen, to offer and sell, from time to time at the Company’s sole discretion, shares of its common stock,
having an aggregate offering price of up to $75.0 million through Cowen as its sales agent. Sales under the Prior ATM Agreement are
deemed to be “at the market offerings,” as defined in Rule 415 under the Securities Act of 1933, as amended, or the Securities Act. Under
the Prior ATM Agreement, the Company was required to pay Cowen a commission of up to three percent of the gross sales proceeds and
provided Cowen with customary indemnification rights. In 2018, the Company issued and sold 11.4 million shares of common stock under
the Prior ATM Agreement at a weighted average price per share of $1.80. The net offering proceeds to the Company in 2018 for sales under
the Prior ATM Agreement were approximately $20.0 million after deducting related expenses, including commissions. Sales of common
stock under the Prior ATM Agreement terminated on June 29, 2018 when the Company’s Registration Statement on Form S-3 (File No.
333-225685) was declared effective by the SEC. Accordingly, as of December 31, 2018, there was no remaining capacity available under
this ATM facility.

 In June 2018, the Company filed a $175.0 million shelf registration statement that included an ATM sales facility to offer and sell,

from time to time at the Company’s sole discretion, shares of its common stock having an aggregate offering price of up to $50.0 million.
Sales of the shares are deemed to be “at the market offerings,” as defined in Rule 415 under the Securities Act. During 2018, the Company
sold approximately 8.5 million shares under this facility, at a weighted average share price of $1.60, which yielded net proceeds to the
Company of approximately $13.2 million after deducting related expenses, including commissions. As of December 31, 2018, there was
approximately $36.4 million of available capacity under this ATM facility.

Equity Incentive Plans

In 2008, the Company adopted the 2008 Equity Incentive Plan, as amended on February 29, 2008, January 7, 2010, July 8, 2010,

December 10, 2010, June 23, 2011 and June 17, 2013, collectively, the 2008 Plan, that authorized the Company to grant restricted stock and
stock options to eligible employees, directors and consultants to the Company.

In 2013, the Company adopted the 2013 Equity Incentive Plan, as amended on May 14, 2014, collectively, 2013 Plan. The 2013

Plan became effective upon the Company’s entry into the underwriting agreement related to its IPO in January 2014 and, as of such date, no
further grants were permitted under the 2008 Plan. The 2013 Plan provides for the grant of incentive stock options, nonstatutory stock
options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance-based stock awards and other forms of
equity compensation (collectively, stock awards), all of which may be granted to employees, including officers, non-employee directors and
consultants of the Company. Additionally, the 2013 Plan provides for the grant of cash and stock based performance awards. The 2013 Plan
contains an “evergreen” provision, pursuant to which the number of shares of common stock available for issuance under the plan
automatically increases on January 1 of each year beginning in 2015.

On December 15, 2016, the Company adopted the Trevena, Inc. Inducement Plan, or the Inducement Plan, effective January 1,

2017, pursuant to which the Company reserved 500,000 shares of the Company’s common stock for issuance under the Inducement Plan.
The Plan provides for nonstatutory stock options and restricted stock unit awards. The only persons eligible to receive grants of awards
under the Inducement Plan are individuals who satisfy the standards for inducement grants under Nasdaq Marketplace Rule 5635(c)(4) and
the related guidance under Nasdaq IM 5635‑1, including individuals who were not previously an employee or director of the Company or
are following a bona

fide period of non-employment, in each case as an inducement material to such individual’s agreement to enter into employment with the
Company.

Under all Plans, the amount, terms of grants and exercisability provisions are determined by the board of directors or its designee.

The term of the options may be up to 10 years, and options are exercisable in cash or as otherwise determined by the board of directors or
its designee. Vesting generally occurs over a period of not greater than four years. For performance-based stock awards, the Company
recognizes expense when achievement of the performance factor is probable, over the requisite service period.

The estimated grant‑date fair value of the Company’s share‑based awards is amortized ratably over the awards’ service periods.

Share‑based compensation expense recognized was as follows (in thousands):

The intrinsic value of the options exercisable as of December 31, 2018 was immaterial, based on the Company’s closing stock

price of $0.43 per share and a weighted average exercise price of $5.08 per share.

The Company uses the Black‑Scholes option‑pricing model to estimate the fair value of stock options at the grant date. The

Black‑Scholes model requires the Company to make certain estimates and assumptions, including estimating the fair value of the
Company’s common stock, assumptions related to the expected price volatility of the Company’s stock, the period during which the options
will be outstanding, the rate of return on risk‑free investments and the expected dividend yield for the Company’s stock.

The per-share weighted-average grant date fair value of the options granted to employees and directors during the year ended

December 31, 2018, 2017 and 2016 was estimated at $1.13, $2.68 and $5.26 per share, respectively, on the date of grant using the Black-
Scholes option-pricing model with the following weighted-average assumptions:

Expected term of options (in years)

The weighted‑average valuation assumptions were determined as follows:

·

·

·

·

·

Risk‑free interest rate: The Company based the risk‑free interest rate on the interest rate payable on U.S. Treasury securities in
effect at the time of grant for a period that is commensurate with the assumed expected option term.

Expected term of options: Due to its lack of sufficient historical data, the Company estimates the expected life of its employee
stock options using the “simplified” method, as prescribed in Staff Accounting Bulletin No. 107, whereby the expected life equals
the arithmetic average of the vesting term and the original contractual term of the option.

Expected stock price volatility: The Company estimated the expected volatility base on its actual historical volatility of the
Company’s stock price. The Company calculated the historical volatility by using daily closing prices over a period of the
expected term of the associated award. Prior to January 1, 2018, the Company estimated the expected volatility based on actual
historical volatility of the stock price of similar companies with publicly‑traded equity securities. The Company calculated the
historical volatility of the selected companies by using daily closing prices over a period of the expected term of the associated
award. The companies were selected based on their enterprise value, risk profiles, position within the industry and with historical
share price information sufficient to meet the expected term of the associated award. A decrease in the selected volatility would
have decreased the fair value of the underlying instrument. The impact of this change had an immaterial effect on the Company’s
financial results for the year ended December 31, 2018.

Expected annual dividend yield: The Company estimated the expected dividend yield based on consideration of its historical
dividend experience and future dividend expectations. The Company has not historically declared or paid dividends to
stockholders. Moreover, it does not intend to pay dividends in the future, but instead expects to retain any earnings to invest in the
continued growth of the business. Accordingly, the Company assumed an expected dividend yield of 0.0%.

Estimated forfeiture rate: In 2016, upon adoption of ASU 2016‑09, the Company elected to record forfeitures upon occurrence,
rather than utilizing an estimate.

The fair value of the Company’s common stock, prior to the IPO, was determined by its board of directors with assistance from its
management. The board of directors and management considered numerous objective and subjective factors in the assessment of fair value,
including the price for the Company’s preferred stock that was sold to investors and the rights, preferences and privileges of the preferred
stock and common stock, the Company’s financial condition and results of operations during the relevant periods and the status of strategic
initiatives. These estimates involved a significant level of judgment.

As of December 31, 2018, there was $5.9 million of total unrecognized compensation expense related to unvested stock options

that will be recognized over the weighted average remaining period of 2.13 years.

Restricted Stock Units

On December 6, 2018, the Company granted 1,255,000 restricted stock unit awards, or RSUs, to employees. The units vest subject
to the satisfaction of service requirements as follows: 25% vest on June 1, 2019, 25% vest on December 1, 2019, and the remaining vest on
December 6, 2021. The closing price of the Company’s common stock on the date of the grant was $0.64 per share, which is the fair market
value per unit of the RSUs.

For the year ended December 31, 2018, the Company recorded less than $0.1 million in stock-based compensation expense related

to RSUs, which is reflected in the statement of operations. As of December 31, 2018, there were 1,255,000 RSUs outstanding.

As of December 31, 2018, there was $0.8 million of total unrecognized compensation expense related to unvested restricted stock

units that will be recognized over the weighted average remaining period of 1.93 years.

On May 3, 2013, the Company entered into an agreement with Allergan plc (formerly Actavis plc and Forest Laboratories

Holdings Limited) (“Allergan”), under which the Company granted to Allergan an exclusive option to license TRV027. Under the option
agreement, the Company conducted, at its expense, a Phase 2b trial of TRV027 in acute heart failure. In March 2015, Allergan and the
Company signed a letter agreement pursuant to which Allergan paid the Company $10.0 million to fund the expansion of the Phase 2b trial
of TRV027 from 500 patients to 620 patients. Collaboration revenue was recognized on a straight-line basis over the study period and was
fully recognized as of June 30, 2016. In August 2016, Allergan notified the Company of its decision not to exercise its option, and the
Company therefore has retained all rights to TRV027.

License and Commercialization Agreement with Pharmbio Korea Inc.

In April 2018, the Company entered into an exclusive license agreement with Pharmbio Korea Inc., or Pharmbio, for the
development and commercialization of oliceridine for the management of moderate-to-severe acute pain in South Korea. Under the terms of
the agreement, the Company received an upfront, non-refundable cash payment of $3.0 million (less applicable withholding taxes of $0.5
million) in June 2018, and will receive a cash commercial milestone of up to $0.5 million if oliceridine is approved in South Korea and
tiered royalties on product sales in South Korea ranging from high single digits to 20%, less applicable withholding taxes. As part of the
agreement, Trevena also granted Pharmbio an option to manufacture oliceridine, on a non-exclusive basis, for the development and
commercialization of the product in South Korea, subject to a separate arrangement to be entered into if Pharmbio exercises the option. The
license agreement is terminable by Pharmbio for any reason upon 180 days written notice.

In accordance with the terms of the agreement, Pharmbio is solely responsible for all development and regulatory activities in
South Korea. The parties have formed a Joint Development Committee with equal representation from the Company and Pharmbio to
provide overall coordination and oversight of the development of oliceridine in South Korea. The parties also agreed to form a Joint
Manufacturing and Commercialization Committee at least six months prior to the anticipated date of regulatory approval of oliceridine in
South Korea to provide overall coordination and oversight of the manufacture and commercialization of oliceridine in South Korea.

See Note 9 for accounting analysis under ASC 606.

License Agreement with Jiangsu Nhwa Pharmaceutical Co. Ltd.

In April 2018, the Company also entered into an exclusive license agreement with Jiangsu Nhwa Pharmaceutical Co. Ltd., or

Nhwa, for the development and commercialization of oliceridine for the management of moderate-to-severe acute pain in China. Under this
agreement, the Company received an upfront, non-refundable cash payment of $2.5 million (less applicable withholding taxes of $0.3
million) in July 2018, and is eligible to receive cash milestone payments of $3.0 million upon regulatory approval of oliceridine in each of
the United States and China, up to an additional $6.0 million of commercialization milestones based on product sales levels in China, and a
ten percent royalty on all net product sales in China, less applicable withholding taxes. As part of the agreement, Trevena also granted Nhwa
an option to manufacture oliceridine, on an exclusive basis in China, for the development and commercialization of the product in China. In
the second quarter of 2018, Nhwa elected to exercise this manufacturing option and the Company and Nhwa expect to enter into a separate
agreement. The license agreement is terminable by Nhwa for any reason upon 180 days written notice.

In accordance with the terms of the agreement, Nhwa is solely responsible for all development and regulatory activities in China.

The parties have formed a Joint Development Committee with equal representation from the Company and Nhwa to provide overall
coordination and oversight of the development of oliceridine in China. The parties also agreed to form a Joint Manufacturing and
Commercialization Committee at least six months prior to the anticipated date of regulatory approval of oliceridine in China to provide
overall coordination and oversight of the manufacture and commercialization of oliceridine in China.

See Note 9 for accounting analysis under ASC 606.

Operating Leases

Lease Expense

The Company leases office space in Pennsylvania. The Company’s leases contain escalating rent clauses, which require higher rent

payments in future years. The Company expenses rent on a straight‑line basis over the term of the lease, including any rent‑free periods.

The Company’s principal office is located at 955 Chesterbrook Boulevard, Chesterbrook, Pennsylvania, where the Company

currently leases approximately 8,231 square feet of developed office space on the first floor and 40,565

99

 
Table of Contents

square feet of developed office space on the second floor. The lease term for this space extends through May 2028. On October 11, 2018,
the Company entered into an agreement with The Vanguard Group, Inc., or Vanguard, whereby Vanguard agreed to sublease the 40,565
square feet of space on the second floor for an initial term of 37 months. Vanguard has an option to extend the sublease term for 3 years, and
a second option to extend the sublease until November 30, 2027. The sublease provides for rent abatement for the first month of the term;
thereafter, the rent payable to the Company by Vanguard under the sublease is (i) $0.50 less during months 2 through 13 of the sublease and
(ii) in month 14 and thereafter of the sublease, $1.00 less than the base rent payable by the Company under its master lease with
Chesterbrook Partners, L.P. Vanguard also is responsible for paying to the Company all tenant energy costs, annual operating costs, and
annual tax costs attributable to the subleased space during the term of the sublease.

In October 2017, the Company terminated its lease related to vivarium space in Exton, Pennsylvania, under an agreement expiring
on December 31, 2018. The Company incurred termination fees equivalent to three months’ rent, totaling less than $0.1 million, in relation
to the early termination of this agreement. Additionally, in November 2017, the Company provided notice of its intent to terminate its
facility lease of approximately 16,714 square feet of office and laboratory space in King of Prussia, Pennsylvania, under an agreement that
expires in September 2020. The Company paid the landlord a $0.15 million termination fee on the date the Company exercised the
termination option. This lease was deemed terminated on August 15, 2018.

Rent expense under operating leases was $1.5 million, $1.3 million and $0.6 million in 2018, 2017 and 2016, respectively.

Future minimum lease payments under noncancelable lease agreements as of December 31, 2018, are as follows (in thousands):

Legal Proceedings

In October and November 2018, the Company and certain of its current and former officers were sued in three purported class
actions filed in the U.S. District Court for the Eastern District of Pennsylvania, or the EDPA. In each case, the plaintiffs allege that the
Company and the officers made false and misleading statements in violation of federal securities laws regarding the Company’s business,
operations, and prospects, including certain statements made relating to the Company’s End-of-Phase 2 meeting with the FDA. The
plaintiffs seek, among other remedies, unspecified damages, and attorneys’ fees and other costs. In January 2019, the three lawsuits were
consolidated into one action. On March 6, 2019, the District Court held a hearing to appoint the lead plaintiff and lead counsel, and a
consolidated amended complaint will be filed after such appointments are made. The Company believes that the lawsuits are without merit,
and it intends to vigorously defend itself against the allegations.

In December 2018, a shareholder derivative action was filed on behalf of the Company and against certain current and former
officers and directors in the EDPA, and in February 2019, two additional, similar shareholder derivative actions were filed in the U.S.
District Court for the District of Delaware. These cases, which involve similar facts as the consolidated securities lawsuits, assert claims
against the individual defendants for, among other things, breach of fiduciary duty, waste of corporate assets, violations of the federal
securities laws, and unjust enrichment, and they make a number of demands, including for monetary damages and other equitable and
injunctive relief. Two of the derivative actions have been stayed in favor of the consolidated securities lawsuits, and the Company expects
that the third derivative action will be stayed as well.

9. Revenue

The Company accounts for revenue under FASB’s ASC 606, Revenue from Contracts with Customers, or ASC 606, under which

revenue is recognized when, or as, performance obligations under the terms of a contract are satisfied, which occurs when control of the
promised products or services is transferred to customers.

 License Revenue recorded under ASC 606

License revenue for the year ended December 31, 2018 represents revenue from contracts with customers in licensing
arrangements accounted for in accordance with ASC 606, which the Company adopted in the first quarter of 2018, as more fully described
in Note 2 and Note 8.  For the year ended December 31, 2018, the Company recognized $3.0 million related to its agreement with Pharmbio
and $2.7 million related to its agreement with Nhwa. There was no license revenue activity in 2017.

Revenue related to the Pharmbio agreement was recognized in the third quarter of 2018, when the Company satisfied its
performance obligation in July 2018. Revenue related to the upfront payments received from Nhwa was recognized in the second quarter of
2018, once the related performance obligation was satisfied in June 2018. Both of these performance obligations were satisfied once the
Company had transferred the license and know-how and each party could begin to benefit from the transfer. The Company determined that
participation in the Joint Development Committees and Joint Manufacturing and Commercialization Committees were deemed immaterial
in the context of the contract.. The income tax expense resulting from these transactions represents foreign withholding taxes as a result of
license revenue from the contracts. As the Company has incurred losses in recent years, no material U.S. federal, state, or foreign income
taxes have been accrued.

Collaboration Revenue recorded under ASC 605

The Company entered into a letter agreement with Allergan in March 2015 under which the Company received a nonrefundable

upfront fee of $10.0 million. The terms of this agreement contained multiple deliverables which included (i) research and development
activities and (ii) testing and analysis related to a Phase 2b trial of TRV027. Collaboration revenue is recognized only when the price is
fixed or determinable, persuasive evidence of an arrangement exists, delivery has occurred or the services have been rendered and the
Company has fulfilled its performance obligations under the contract. The Allergan collaboration revenue was recorded on a straight-line
basis and was fully recognized as of June 30, 2016.

10. Restructuring Charges

On November 8, 2018, upon the approval of the Company's Board of Directors, the Company announced a restructuring of
approximately one-third of the Company's workforce, or 14 employees, as well as other cost saving initiatives intended to lower the
Company's annualized net operating cash burn. The Company completed the restructuring on December 31, 2018. The Company has
determined that the total costs related to the restructuring are approximately $1.4 million, all of which is expected to result in future cash
outlays, primarily related to severance costs and benefit-related expenses. The Company recorded these charges in the fourth quarter of
2018.

On October 11, 2017, upon the approval of the Company’s Board of Directors, the Company announced a restructuring and

reduction in force of approximately 30% of the Company’s workforce, or 21 employees. As part of this restructuring, the Company also
halted its investment in early stage research. The Company incurred pre-tax restructuring charges of $1.8 million during the year ended
December 31, 2017, primarily related to severance and personnel related costs in addition to lease termination payments, as detailed below.

In October 2017, in connection with the Company’s restructuring and reduction in force, the Company terminated its lease related

to vivarium space in Exton, Pennsylvania, under an agreement expiring on December 31, 2018. The Company incurred termination fees
equivalent to three months’ rent, totaling less than $0.1 million, in relation to the early termination of this agreement.

Additionally, in November 2017, the Company provided notice of its intent to terminate its facility lease of approximately 16,714

square feet of office and laboratory space in King of Prussia, Pennsylvania, under an agreement that expires in September 2020. The
Company paid the landlord a $0.15 million termination fee on the date the Company exercised the termination option. As a result, this lease
was deemed terminated on August 15, 2018.

There were no reclassifications out of accumulated other comprehensive income or loss as well as no tax effect for all periods

presented.

13. Income Taxes

 As the Company has historically incurred net operating losses, the Company has not recorded a provision for income taxes.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation, the Tax Cuts and Jobs Act, or the Tax Act.
The Tax Act makes broad and complex changes to the U.S. tax code, including, but not limited to, (1) reducing the U.S. federal corporate
tax rate to 21 percent, (2) elimination of the corporate alternative minimum tax, or AMT, and changing how existing AMT credits can be
realized; (3) a new limitation on deductible interest expense; (4) the repeal of the domestic production activity deduction; (5) creating the
base erosion and anti-abuse tax, or BEAT, a new minimum tax; (6) limitation on the deductibility of certain executive compensation; (7)
enhancing the option to claim accelerated depreciation deductions on qualified property and (8) limitations on net operating losses, or NOLs,
generated after December 31, 2017, to 80 percent of taxable income.

The income tax provision for the years ended December 31, 2018 and 2017 are as follows (in thousands):

Deferred tax assets and liabilities reflect the net effects of net operating loss and tax credit carryovers and temporary differences
between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The
Company maintains a full valuation allowance against its net deferred tax assets because significant utilization of such amounts is not
presently expected in the foreseeable future.

Significant components of the Company’s net deferred tax assets as of December 31, 2018 are as follows (in thousands):

Deferred tax assets:

Net operating loss carryforwards
Research and development credits
Research and development expenses capitalized for tax purposes
Deferred rent
Depreciation
Other temporary differences

As of December 31, 2018, the Company had federal and state net operating loss carryforwards of $65.5 million and $65.6 million

that begin to expire at various dates starting in 2028. As of December 31, 2018, the Company had federal research and development tax
credit carryforwards of $13.1 million that begin to expire at various dates starting in 2028. The Company’s ability to utilize net operating
loss carryforwards, or NOLs, or tax credit carryforwards may be subject to annual limitations under certain provisions of the Internal
Revenue Code related to “changes in ownership.”

The Company files income tax returns in the U.S. and the Commonwealth of Pennsylvania. Tax years for fiscal 2015 through 2017
are open and potentially subject to examination by the federal and state taxing authorities. The Company is currently not under examination
by the Internal Revenue Service or any other jurisdictions for any tax years. To the extent the Company utilizes in the future any tax
attribute NOL carryforwards from a tax period that may otherwise be closed to examination, the Internal Revenue Service, state tax
authorities, or other governing parties may still adjust the NOL carryforwards upon their examination of the future period in which the
attribute was utilized. There are no uncertain tax positions recorded for any federal or state items.

The quarters presented above have been adjusted to reflect the adoption of ASU 2016‑09 and related impact, that is deemed

immaterial, of electing to recognize forfeitures of share-based payment awards as they occur rather than using an estimate.

16. Subsequent Events

On January 29, 2019, the Company entered into securities purchase agreements with two institutional investors wherein the

Company agreed to sell to the investors an aggregate of 10,000,000 shares of its common stock, at an offering price of $1.00 per share, in a
registered direct offering made pursuant to the Company’s existing registration statement on Form S-3. The net proceeds to the Company
from the offering were approximately $9.2 million, after deducting after deducting fees and the expenses of the placement agent. The
Company intends to use the net proceeds from the offering primarily for the development of oliceridine and for general corporate purposes.

Pursuant to a letter agreement dated January 28, 2019, the Company engaged H.C. Wainwright & Co., LLC, or Wainwright, to act

as its exclusive placement agent in connection with the issuance and sale of the shares. The Company paid Wainwright 7.0% of the
aggregate gross proceeds in the offering and $50,000 for certain expenses, and it issued warrants to purchase 500,000 shares of common
stock to certain designees of Wainwright. These warrants have a term of five years, are immediately exercisable and have an exercise price
of $1.25 per share. The letter agreement also includes indemnification obligations of the Company and other provisions customary for
transactions of this nature.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL
DISCLOSURE 

None.

ITEM 9A. CONTROLS AND PROCEDURES 

Evaluation of Disclosure Controls and Procedures

An evaluation was performed under the supervision and with the participation of our management, including our Chief Executive

Officer, or CEO, and our Vice President, Finance (Principal Financial Officer and Accounting Officer), of the effectiveness of our
disclosure controls and procedures, as such term is defined under Rule 13a‑15(e) promulgated under the Exchange Act as of December 31,
2018.

Based on that evaluation, our management, including our CEO and Vice President, Finance, concluded that as of December 31,
2018 our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports that we file
or submit under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the rules and forms
of the Securities and Exchange Commission and that such information is accumulated and communicated to the Company’s management,
including our CEO and Vice President, Finance, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting during our most recent fiscal quarter that have

materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting and Attestation Report of the Registered Public Accounting
Firm

Management’s Report on Internal Control Over Financial Reporting is included in Part II, Item 8 of this Annual Report on

Form 10‑K and incorporated into this Item 9A by reference.

firm.

EXECUTIVE EMPLOYMENT AGREEMENT

This Agreement is entered into as of April 26, 2018 by and between Trevena, Inc. (the “Company”),  a
Delaware corporation, and Mark A. Demitrack (“Executive”) and will become effective as of May 21, 2018 (the
“Effective Date”).

WHEREAS, the Company desires to employ Executive to provide personal services to the Company, and
Executive wishes to continue to be employed by the Company and provide personal services to the Company in
return for certain compensation and benefits.

Accordingly, in consideration of the mutual promises and covenants contained herein, the parties agree to

the following:

1.

 Duties and Scope of Employment.

(a)  Positions and Duties.  Effective as of the Effective Date, Executive will serve as Senior Vice
President  &  Chief  Medical  Officer  of  the  Company.    Executive  will  render  such  business  and  professional
services in the performance of Executive’s duties, consistent with Executive’s position within the Company, as
will reasonably be assigned to Executive by the Company’s Chief Executive Officer, to whom Executive will
report.  The period of Executive’s employment under this Agreement is referred to herein as the “ Employment
Term.” 

(b)   Obligations.    During  the  Employment  Term,  Executive  will  perform  Executive’s  duties
faithfully and to the best of Executive’s ability.  For the duration of the Employment Term, Executive agrees not
to  actively  engage  in  any  other  employment,  occupation  or  consulting  activity  for  any  direct  or  indirect
remuneration  without  the  prior  approval  of  the  Company’s  Board  of  Directors  (the  “Board”)  or  the
Compensation  Committee  of  the  Board  (the  “Compensation  Committee”).    Nothing  in  this  Agreement  or
elsewhere  shall  prevent  Executive  from  managing  his  personal  investment  and  affairs,  or  from  engaging  in
charitable  and  community  affairs,  so  long  as  such  activities  do  not  either  individually  or  in  the  aggregate
interfere with the performance of his duties for the Company.

2.

 At-Will Employment.  The parties agree that Executive’s employment with the Company is “at-will”
employment  and  may  be  terminated  at  any  time  with  or  without  cause  or  notice.    Executive’s  at-will
employment  status  may  not  be  changed  except  by  way  of  written  agreement  signed  by  Executive  and  an
authorized officer of the Company. 

3.

 Compensation.

(a)   Base  Salary.    During  the  Employment  Term,  the  Company  will  pay  Executive  an  initial
annualized salary of $365,000 as compensation for services (the “Base Salary”).  The Base Salary shall be paid
in  equal  installments  in  accordance  with  the  Company’s  normal  payroll  practices  and  subject  to  required
withholding  and  deductions.    The  Base  Salary  will  be  subject  to  review  and  adjustments  will  be  made  based
upon the Company’s normal performance review practices.

 
 
 
(b)   Bonus.    Subject  to  the  terms  and  conditions  set  forth  in  the  Trevena,  Inc.  Incentive
Compensation Plan (the “ICP”), Executive may be eligible to receive an annual bonus in a target amount of 40%
of  the  Base  Salary,  subject  to,  among  other  things,  the  achievement  of  corporate  and  individual  performance
objectives,  which  shall  be  established  and  assessed  by  the  Company  (the  “Target  Bonus”).    For  2018,  such
objectives  will  be  established  within  the  first  thirty  (30)  days  after  the  Effective  Date.    For  each  subsequent
calendar  year,  these  objectives  generally  will  be  established  within  90  days  after  the  start  of  such  calendar
year.  The Company reserves the right to modify the terms of the ICP, the Target Bonus and other components
of bonus compensation and criteria from year to year.  

(c)  Equity Award . Upon approval by the Board of Directors (the “Board”) or the Compensation
Committee  of  the  Board  (the  “Compensation  Committee”),  Employee  will  be  granted  a  nonstatutory  stock
option  to  purchase  200,000  shares  of  Common  Stock,  $0.001  par  value  per  share,  of  the  Company  (the
“Common Stock”), which option is granted under the Trevena, Inc. Inducement Plan (the “Plan”) pursuant to
the inducement grant exception under Nasdaq Rule 5635(c)(4) and not pursuant to the Company’s 2013 Equity
Incentive Plan, as amended or any other equity incentive plan of the Company, as an inducement that is material
to Employee’s employment with the Company (the “Inducement Grant”). The Inducement Grant shall have a
ten-year term, an exercise price equal to the closing price of the Common Stock on the NASDAQ Global Select
Market on the date of such grant and shall vest as to 6.25% of the shares subject to such option on each quarterly
(i.e., every three months) anniversary of the date of grant of the option. The Inducement Grant shall be subject to
such other terms as are customary for the Company’s options under the Plan and the previously approved form
of  stock  option  agreement  under  the  Plan.    Employee  will  be  eligible  to  receive  awards  of  stock  options,
restricted  stock,  or  any  other  equity  award  based  on  Employee’s  performance  as  determined  by  the  Board  or
Compensation Committee from time to time.  The Board or the Compensation Committee will determine in its
discretion whether and when Employee will be granted any such equity awards.

4.

  Company  Policies  and  Employee  Benefits.    During  the  Employment  Term,  Executive  will  be
eligible  to  participate  in  the  employee  benefit  plans  currently  and  hereafter  maintained  by  the  Company  of
general applicability to other senior executives of the Company, including, without limitation, any such group
medical, dental, vision, disability, life insurance, and flexible-spending account plans.  All matters of eligibility
for coverage and benefits under any benefit plan shall be determined in accordance with the provisions of such
plan.    The  Company  reserves  the  right  to  cancel  or  change  the  benefit  plans  and  programs  it  offers  to  its
employees at any time. 

5.

 Vacation.  While employed pursuant to this Agreement, Executive shall be eligible to take vacation

subject to the Company’s vacation policy. 

6.

  Expenses.    The  Company  will  reimburse  Executive  for  reasonable  travel,  entertainment  or  other
expenses  incurred  by  Executive  in  the  furtherance  of  or  in  connection  with  the  performance  of  Executive’s
duties hereunder, in accordance with the Company’s expense reimbursement policy.

7.

 Termination of Employment.  The provisions of this Section 7 govern the amount of compensation
or benefit, if any, to be provided to Executive upon termination of employment and do not affect the right of
either party to terminate the employment relationship at any time for any reason. 

2

 
(a)  Termination for other than Cause, Death or Disability.    If at any time following the Effective
Date (x) the Company terminates Executive’s employment with the Company other than for Cause (as defined
below), death or disability, or (y) Executive terminates his employment under this Agreement for Good Reason,
then, subject to Section 8, Executive will be entitled to   receive, less applicable withholdings and deductions:

(i) 
an amount equal to twelve (12) months of Executive’s annualized Base Salary in effect at
the time of termination, payable in equal installments on the Company’s regularly scheduled payroll
dates beginning with the first payroll date following the effective date of the Release and Waiver; 

(ii)
(A)    a  pro-rata  bonus  for  the  calendar  year  of  termination,  determined  by  multiplying
Executive’s  Target  Bonus  for  such  year  (assuming  employment  for  the  entire  year)  by  a  fraction
whose numerator is the number of days that Executive was employed during such year and whose
denominator is the total number of days in such year, payable within 60 days following the date of
Executive’s termination of employment; and

(B)  to the extent not already paid, a cash incentive award under the Company’s Incentive
Compensation Plan or any similar incentive plan (the “ICP”) related to the fiscal year immediately
preceding  the  year  of  termination  in  an  amount  as  determined  by  the  Company’s  Board  or  the
Compensation Committee of the Board, as the case may be, in its sole judgment and discretion;

(iii) if  Executive  timely  elects  continued  coverage  under  COBRA  for  Executive  and
Executive’s  covered  dependents  under  the  Company’s  group  health  plans  following  such
termination  of  employment,  the  Company  will  pay  the  COBRA  premiums  necessary  to  continue
Executive’s health insurance coverage in effect for Executive and Executive’s eligible dependents
on  the  termination  date,  as  and  when  due  to  the  insurance  carrier  or  COBRA  administrator  (as
applicable), until the earliest of (A) twelve (12) months from the effective date of such termination,
(B) the expiration of Executive’s eligibility for the continuation coverage under COBRA, or (C) the
date  when  Executive  becomes  eligible  for  substantially  equivalent  health  insurance  coverage  in
connection  with  new  employment  or  self-employment  (such  period  from  the  termination  date
through  the  earliest  of  (A)  through  (C),  the  “COBRA  Payment  Period”).  Notwithstanding  the
foregoing,  if  at  any  time  the  Company  determines,  in  its  sole  discretion,  that  the  payment  of  the
COBRA premiums would result in a violation of the nondiscrimination rules of Section 105(h)(2) of
the Code or any statute or regulation of similar effect (including but not limited to the 2010 Patient
Protection  and  Affordable  Care  Act,  as  amended  by  the  2010  Health  Care  and  Education
Reconciliation Act), then in lieu of providing the COBRA premiums, the Company will instead pay
Executive on the last day of each remaining month of the COBRA Payment Period, a fully taxable
cash payment equal to the COBRA premiums for that month, subject to applicable tax withholdings
(such  amount,  the  “Special  Severance  Payment”),  for  the  remainder  of  the  COBRA  Payment
Period;

and

3

 
 
 
 
(iv) accelerated  vesting  as  to  that  number  of  unvested  shares  subject  to  any  outstanding
equity  awards  held  by  Executive  at  the  time  of  termination  that  would  have  otherwise  vested  if
Executive had remained a Company employee for nine (9) months following the termination date.

(b)  Termination in Connection With or Following a Change of Control .    In the event that either
(x)  the  Company  terminates  Executive’s  employment  with  the  Company  other  than  for  Cause,  death  or
disability (A) within the thirty (30) day period prior to a Change of Control, or (B) within the period between
the  Company’s  execution  of  a  letter  of  intent  for  a  proposed  Change  of  Control  which  proposed  Change  of
Control is later consummated (a “Designated Change of Control”) and the consummation of such Designated
Change  of  Control,  or  (C)  within  the  twelve  (12)  month  period  after  a  Change  of  Control,  or  (y)  Executive
resigns for Good Reason within twelve (12) months after a Change of Control, then, in addition to the payments
set forth in Section 7(a) above, and subject to Section 8 below, Executive shall also be entitled to, less applicable
withholdings and deductions:

(i)

 an amount equal to fifteen (15) months of Executive’s annualized Base Salary
in  effect  at  the  time  of  termination,  payable  in  equal  installments  on  the  Company’s  regularly
scheduled  payroll  dates  beginning  with  the  first  payroll  date  following  the  effective  date  of  the
Release and Waiver;

  (A)    a  pro-rata  bonus  for  the  calendar  year  of  termination,  determined  by
(ii)
multiplying  Executive’s  Target  Bonus  for  such  year  (assuming  employment  for  the  entire  year)
by a fraction whose numerator is the number of days that Executive was employed during such
year  and  whose  denominator  is  the  total  number  of  days  in  such  year,  payable  within  60  days
following the date of Executive’s termination of employment; and

(B)  to the extent not already paid, a cash incentive award under the ICP related to the fiscal
year immediately preceding the year of termination in an amount as determined by the Company’s
Board or the Compensation Committee of the Board, as the case may be, in its sole judgment and
discretion;

(iii) 

an amount equal to fifteen (15) months of Executive’s annual Target Bonus in
effect  at  the  time  of  termination,  payable  in  equal  installments  on  the  Company’s  regularly
scheduled  payroll  dates  beginning  with  the  first  payroll  date  following  the  effective  date  of  the
Release and Waiver;

( i v ) if  Executive  timely  elects  continued  coverage  under  COBRA  for  Executive  and
Executive’s  covered  dependents  under  the  Company’s  group  health  plans  following  such
termination  of  employment,  the  Company  will  pay  the  COBRA  premiums  necessary  to  continue
Executive’s health insurance coverage in effect for Executive and Executive’s eligible dependents
on  the  termination  date,  as  and  when  due  to  the  insurance  carrier  or  COBRA  administrator  (as
applicable), until the earliest of (A) fifteen (15) months from the effective date of such termination,
(B) the expiration of Executive’s eligibility for the continuation coverage under COBRA, or (C) the
date when Executive becomes eligible for substantially equivalent health insurance

4

 
coverage  in  connection  with  new  employment  or  self-employment  (such  period  from  the
termination  date  through  the  earliest  of  (A)  through  (C),  the  “COBRA  Payment  Period”).
Notwithstanding the foregoing, if at any time  the  Company  determines,  in  its  sole  discretion,  that
the payment of the COBRA premiums would result in a violation of the nondiscrimination rules of
Section 105(h)(2) of the Code or any statute or regulation of similar effect (including but not limited
to the 2010 Patient Protection and Affordable Care Act, as amended by the 2010 Health Care and
Education Reconciliation Act), then in lieu of providing the COBRA premiums, the Company will
instead pay Executive on the last day of each remaining month of the COBRA Payment Period, a
fully taxable cash payment equal to the COBRA premiums for that month, subject to applicable tax
withholdings  (such  amount,  the  “Special  Severance  Payment”),  for  the  remainder  of  the  COBRA
Payment Period;

and

(v) 

immediate  and  full  accelerated  vesting  of  all  unvested  shares  subject  to  any
outstanding  equity  awards  held  by  Executive  at  the  time  of  termination; provided,   however,  that
such acceleration shall not be interpreted to extend the post-termination exercise period of any stock
option held by Executive at the time of termination, unless otherwise approved by the Board.

(c)   Termination  for  Cause,  Death  or  Disability;  Voluntary  Termination .    If  Executive’s
employment with the Company terminates voluntarily by Executive (other than for Good Reason as set forth in
the preceding subsection (b)), for Cause by the Company or due to Executive’s death or disability, then (i) all
vesting will terminate immediately with respect to Executive’s outstanding equity awards, (ii) all payments of
compensation by the Company to Executive hereunder will terminate immediately (except as to amounts already
earned).

(d)  Termination by Mutual Consent.  If at any time during the course of this Agreement the parties
by mutual consent decide to terminate this Agreement, they shall do so by separate agreement setting forth the
terms and condition of such termination.

8.

 Conditions to Receipt of Benefits under Section 7.

(a)  Release of Claims.  The receipt of any payment or benefit pursuant to Section 7 will be subject
to Executive signing and not revoking a release and waiver of all claims in the form attached hereto as Exhibit A
(or  in  such  other  form  as  may  be  specified  by  the  Company  in  order  to  comply  with  then-existing  legal
requirements to effect a valid release of claims) (the “Release and Waiver”)  within  the  applicable  time  period
set forth therein, but in no event later than forty-five days following termination of employment.  No payment or
benefit pursuant to Section 7 will be paid or provided until the Release and Waiver becomes effective.

(b)  Other Conditions.  The receipt of any payment or benefits pursuant to Section 7 will be subject
to  Executive  not  violating  the  Employee  Proprietary  Information,  Inventions  and  Non-Solicitation Agreement
attached hereto as Exhibit B (the “PIIA”), returning all Company property, and complying with the Release and
Waiver; provided, however, that Company must provide written notice to Executive of the condition under this
Section 8(b) that could prevent the disbursement of any

5

 
payment or benefits under Section 7 within thirty (30) days of the initial existence of such condition and such
condition must not have been remedied by Executive within thirty (30) days of such written notice.  Executive
understands and agrees that payment or benefits received pursuant to Section 7 are in lieu of and not in addition
to  any  severance  or  similar  benefits  that  may  be  provided  to  other  employees  of  the  Company  pursuant  to  a
Company policy or plan.

(c)  Section 409A.   Notwithstanding  anything  to  the  contrary  set  forth  herein,  any  payments  and
benefits provided under Section 7 above that constitute “deferred compensation  ” within the meaning of Section
409A of the Internal Revenue Code of 1986, as amended (the  “Code”) and the regulations and other guidance
thereunder and any state law of similar effect (collectively “Section 409A”) shall not commence in connection
with  Executive’s  termination  of  employment  unless  and  until  Executive  has  also  incurred  a  “separation  from
service”  (as  such  term  is  defined  in  Treasury  Regulation  Section  1.409A-1(h)  (“Separation  From  Service”),
unless  the  Company  reasonably  determines  that  such  amounts  may  be  provided  to  Executive  without  causing
Executive to incur the additional 20% tax under Section 409A.  Pay pursuant to Section 7 above, to the extent of
payments made from the date of termination of Executive’s employment through March 15 of the calendar year
following such termination, are intended to constitute separate payments for purposes of Section 1.409A-2(b)(2)
of  the  Treasury  Regulations  and  thus  payable  pursuant  to  the  “short-term  deferral”  rule  set  forth  in  Section
1.409A-1(b)(4)  of  the  Treasury  Regulations;  to  the  extent  such  payments  are  made  following  said  March  15,
they  are  intended  to  constitute  separate  payments  for  purposes  of  Section  1.409A-2(b)(2)  of  the  Treasury
Regulations made upon an involuntary termination of service and payable pursuant to Section 1.409A-1(b)(9)
(iii) of the Treasury Regulations, to the maximum extent permitted by said provision, with any excess amount
being  regarded  as  subject  to  the  distribution  requirements  of  Section  409A(a)(2)(A)  of  the  Internal  Revenue
Code, including, without limitation, the requirement of Section 409A(a)(2)(B)(i) of the Code that, if  Executive
is  a  “specified  employee”  within  the  meaning  of  the  aforesaid  Section  of  the  Code  at  the  time  of  such
termination  from  employment,  payments  be  delayed  until  the  earlier  of  six  months  after  termination  of
employment  or  Executive’s  death (such  applicable  date,  the “Specified  Employee  Initial  Payment  Date”). 
Notwithstanding any other payment schedule set forth in herein, none of the payments under Section 7 will be
paid  or  otherwise  delivered  prior  to  the  effective  date  of  the  Release  and  Waiver.    Except  to  the  extent  that
payments may be delayed until the Specified Employee Initial Payment Date pursuant to the preceding sentence,
on the first regular payroll pay day following the effective date of the Release and Waiver, the Company will
pay Executive the payments Executive would otherwise have received under Section 7 on or prior to such date
but  for  the  delay  in  payment  related  to  the  effectiveness  of  the  Release  and  Waiver,  with  the  balance  of  the
payments being paid as originally scheduled.  Notwithstanding anything to the contrary set forth herein, if any
of  the  payments  or  benefits  set  forth  in  Section  7  constitute  “deferred  compensation”  within  the  meaning  of
Section 409A of the Code and the period during which Executive may review, execute and revoke the Release
and  Waiver  begins  in  one  taxable  year  and  ends  in  a  second  taxable  year,  such  payments  and  benefits  shall
commence or be made in the second taxable year.

(d)  Cooperation with the Company After Termination of Employment .  Following termination of
the Executive’s employment for any reason, upon request by the Company, Executive will fully cooperate with
the  Company  (at  the  Company’s  reasonable  expense)  in  all  matters  reasonably  relating  to  the  winding  up  of
pending  work  including,  but  not  limited  to,  any  litigation  in  which  the  Company  is  involved,  and  the  orderly
transfer of any such pending work to such other employees as may be designated by the Company.

 Definitions.  

(a)   Cause.    For  purposes  of  this Agreement,  “Cause”  is  defined  as  (i)  an  act  of  dishonesty  by
Executive in connection with Executive’s responsibilities as an employee, (ii) Executive’s conviction of, or plea
of nolo contendere to, a felony or any crime involving fraud, embezzlement or any other act of moral turpitude,
(iii)  Executive’s  gross  misconduct,  (iv)  Executive’s  unauthorized  use  or  disclosure  of  any  proprietary
information  or  trade  secrets  of  the  Company  or  any  other  party  to  whom  Executive  owes  an  obligation  of
nondisclosure as a result of Executive’s relationship with the Company, or (v) Executive’s willful breach of any
obligations under any written agreement or covenant with the Company.

(b)  Change of Control.  For purposes of this Agreement, “Change of Control” of the Company is

defined as:

(i)

 any “person” (as such term is used in Sections 13(d) and 14(d) of the Securities
Exchange Act of 1934, as amended) is or becomes the “beneficial owner” (as defined in Rule 13d-3 under said
Act),  directly  or  indirectly,  of  securities  of  the  Company  representing  50%  or  more  of  the  total  voting  power
represented by the Company’s then outstanding voting securities; provided, however; that sales of equity or debt
securities to investors primarily for capital raising purposes shall in no event be deemed a Change of Control; or

(ii)

 a change in the composition of the Board occurring within a two-year period, as a
result  of  which  less  than  a  majority  of  the  directors  are  Incumbent  Directors.    “Incumbent  Directors”  will
mean  directors  who  either  (A)  are  directors  of  the  Company  as  of  the  date  hereof,  or  (B)  are  elected,  or
nominated for election, to the Board with the affirmative votes of at least a majority of the Incumbent Directors
at the time of such election or nomination (but will not include an individual whose election or nomination is in
connection  with  an  actual  or  threatened  proxy  contest  relating  to  the  election  of  directors  to  the  Company);
provided, however; that no change in the composition of the Board in connection with the sale of equity or debt
securities to investors primarily for capital raising purposes shall be deemed a Change of Control; or

(iii)

 the date of the consummation of a merger or consolidation of the Company with
any  other  corporation  that  has  been  approved  by  the  stockholders  of  the  Company,  other  than  a  merger  or
consolidation which would result in the voting securities of the Company outstanding immediately prior thereto
continuing  to  represent  (either  by  remaining  outstanding  or  by  being  converted  into  voting  securities  of  the
surviving entity) more than fifty percent (50%) of the total voting power represented by the voting securities of
the  Company  or  such  surviving  entity  outstanding  immediately  after  such  merger  or  consolidation  or  the
stockholders of the Company approve a plan of complete liquidation of the Company; or

substantially all the Company’s assets.

(iv)

 the date of the consummation of the sale or disposition by the Company of all or

(c)  Good Reason.  For purposes of this Agreement, a resignation for “Good Reason” is defined as
the resignation by Executive within thirty (30) days following the end of the Cure Period (defined below), if any
of the following events occur without Executive’s express written consent:  (i) the Company reduces the amount
of the Base Salary, other than pursuant to a reduction

7

 
that also is applied to substantially all other executives of the Company, (ii) the Company fails to pay the Base
Salary or other benefits required to be provided by the Company hereunder, (iii) the Company materially
reduces Executive’s core functions, duties or responsibilities in a manner that constitutes a demotion, or (iv) any
change of Executive’s principal office location to a location more than thirty (30) miles from the Company’s

provide written notice to the Company of the condition that could constitute “Good Reason” within thirty (30)
days of the initial existence of such condition and such condition must not have been remedied by the Company
within thirty (30) days of such written notice (the “Cure Period”).                

10.  No Conflict with Existing Obligations.  Executive represents that his performance of all the terms of
this  Agreement  and,  as  an  executive  officer  of  the  Company,  do  not  and  will  not  breach  any  agreement  or
obligation  of  any  kind  made  prior  to  Executive’s  employment  by  the  Company,  including  agreements  or
obligations  Executive  may  have  with  prior  employers  or  entities  for  which  Executive  has  provided
services.  Executive has not entered into, and Executive agrees that Executive will not enter into, any agreement
or obligation, either written or oral, in conflict herewith.

11.  Parachute Payments.

(a)

If  any  payment  or  benefit  Executive  would  receive  pursuant  to  a  Change  of
Control  from  the  Company  or  otherwise  (“Payment”)  would  (i)  constitute  a  “parachute  payment”  within  the
meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), and (ii) but for this
sentence,  be  subject  to  the  excise  tax  imposed  by  Section  4999  of  the  Code  (the  “Excise  Tax ”),  then  such
Payment  shall  be  reduced  to  the  Reduced  Amount.    The  “Reduced  Amount”  shall  be  either  (x)  the  largest
portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax or (y) the
largest  portion,  up  to  and  including  the  total,  of  the  Payment,  whichever  amount,  after  taking  into  account  all
applicable  federal,  state  and  local  employment  taxes,  income  taxes,  and  the  Excise  Tax  (all  computed  at  the
highest applicable marginal rate), results in Executive’s receipt, on an after-tax basis, of the greater amount of the
Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction
in payments or benefits constituting “parachute payments” is necessary so that the Payment equals the Reduced
Amount,  reduction  shall  occur  in  the  following  order  unless  Executive  elects  in  writing  a  different  order
(provided, however, that such election shall be subject to Company approval if made on or after the date on which
the event that triggers the Payment occurs):  reduction of cash payments; cancellation of accelerated vesting of
stock  awards;  reduction  of  employee  benefits.    In  the  event  that  acceleration  of  vesting  of  stock  award
compensation is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of the date of
grant of Executive’s stock awards unless Executive elects in writing a different order for cancellation.

(b)

The accounting firm engaged by the Company for general audit purposes as of
the  day  prior  to  the  effective  date  of  the  Change  of  Control  shall  perform  the  foregoing  calculations.    If  the
accounting firm so engaged by the Company is serving as accountant or auditor for the individual, entity or group
affecting the Change of Control, the Company shall appoint a nationally recognized accounting firm to make the
determinations required hereunder.  The Company shall bear all expenses with respect to the determinations by
such accounting firm required to be made hereunder.

8

 
 
(c)

The  accounting  firm  engaged  to  make  the  determinations  hereunder  shall  provide
its  calculations,  together  with  detailed  supporting  documentation,  to  the  Company  and  Executive  within  fifteen
(15) calendar days after the date on which Executive’s right to a Payment is triggered (if requested at that time by
the Company or Executive) or such other time as requested by the Company or Executive.  If the accounting firm
determines that no Excise Tax is payable with respect to a Payment, it shall furnish the Company and Executive
with  an  opinion  reasonably  acceptable  to  Executive  that  no  Excise  Tax  will  be  imposed  with  respect  to  such
Payment.    Any  good  faith  determinations  of  the  accounting  firm  made  hereunder  shall  be  final,  binding  and
conclusive upon the Company and Executive.

12.  Assignment.  This Agreement will be binding upon and inure to the benefit of (a) the heirs, executors
and legal representatives of Executive upon Executive’s death and (b) any successor of the Company.  Any such
successor of the Company will be deemed substituted for the Company under the terms of this Agreement for all
purposes.  For this purpose, “successor” means any person, firm, corporation or other business entity which at
any time, whether by purchase, merger or otherwise, directly or indirectly acquires all or substantially all of the
assets  or  business  of  the  Company.    None  of  the  rights  of  Executive  to  receive  any  form  of  compensation
payable  pursuant  to  this Agreement  may  be  assigned  or  transferred  except  by  will  or  the  laws  of  descent  and
distribution.  Any other attempted assignment, transfer, conveyance or other disposition of Executive’s right to
compensation or other benefits will be null and void.

13.  Notices.  All notices, requests, demands and other communications called for hereunder will be in
writing and will be deemed given (i) on the date of delivery if delivered personally, (ii) one (1) day after being
sent  by  a  nationally  recognized  commercial  overnight  service,  specifying  next  day  delivery,  with  written
verification  of  receipt,  or  (iii)  four  (4)  days  after  being  mailed  by  registered  or  certified  mail,  return  receipt
requested, prepaid and addressed to the parties or their successors at the following addresses, or at such other
addresses as the parties may later designate in writing:

If to the Company:

955 Chesterbrook Blvd, Suite 200, Chesterbrook, PA 19087
Attn: General Counsel

If to Executive:

at the last residential address known by the Company.

14.  Severability.  In the event that any provision of this Agreement becomes or is declared by a court of
competent jurisdiction to be illegal, unenforceable or void, this Agreement will continue in full force and effect
without said provision.

15.  Arbitration.

(a)  Arbitration.  In consideration of Executive’s employment with the Company, the Company and
Executive agree that any and all controversies, claims, or disputes with anyone (including the Company and any
employee, officer, director, shareholder or benefit plan of the Company in their capacity as such or otherwise)
arising  out  of,  relating  to,  or  resulting  from  Executive’s  employment  with  the  Company  or  the  termination  of
Executive’s employment with the

9

 
Company, including any breach of this Agreement, but not including those arising out of, relating to, or resulting
from the PIAA, will be subject to binding arbitration.  Disputes which Executive agrees to arbitrate, and thereby
agrees to waive any right to a trial by jury, include any statutory claims under state or federal law, including, but
not limited to, claims under Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act of
1990,  the  Age  Discrimination  in  Employment  Act  of  1967,  the  Older  Workers  Benefit  Protection  Act,  the
Worker  Adjustment  and  Retraining  Notification  Act,  the  Family  and  Medical  Leave  Act,  discrimination  or
wrongful termination and any statutory claims.  Executive further understands that this Agreement to arbitrate
also applies to any disputes that the Company may have with Executive.

(b)   Procedure.    Executive  agrees  that  any  arbitration  will  be  administered  by  the  American
Arbitration Association (“AAA”) and that the neutral arbitrator will be selected in a manner consistent with its
National Rules for the Resolution of Employment Disputes (the “Rules”).  Executive agrees that the arbitrator
will administer and conduct any arbitration in a manner consistent with the Rules.

(c)  Remedy.  Except as provided by this Agreement and by the Rules, including any provisional
relief offered therein, arbitration will be the sole, exclusive and final remedy for any dispute between Executive
and the Company.  Accordingly, except as provided for by the Rules and this Agreement, neither Executive nor
the Company will be permitted to pursue court action regarding claims that are subject to arbitration. 

(d)  Administrative Relief.  Executive understands that this Agreement does not prohibit Executive
from  pursuing  an  administrative  claim  with  a  local,  state  or  federal  administrative  body  such  as  the  Equal
Employment  Opportunity  Commission  or  the  workers’  compensation  board.    This Agreement  does,  however,
preclude Executive from pursuing court action regarding any such claim.

(e)   Voluntary  Nature  of  Agreement .    Executive  acknowledges  and  agrees  that  Executive  is
executing  this Agreement  voluntarily  and  without  any  duress  or  undue  influence  by  the  Company  or  anyone
else.    Executive  further  acknowledges  and  agrees  that  Executive  has  carefully  read  this Agreement  and  that
Executive  has  asked  any  questions  needed  for  Executive  to  understand  the  terms,  consequences  and  binding
effect of this Agreement and fully understands it, including that  Executive is waiving Executive’s right to a jury
trial.    Finally,  Executive  agrees  that  Executive  has  been  provided  an  opportunity  to  seek  the  advice  of  an
attorney of Executive’s choice before signing this Agreement.

16.   Integration.    This Agreement,  together  with  the  PIIA  and  the  other  documents  referred  to  in  this
Agreement,  represents  the  entire  agreement  and  understanding  between  the  parties  as  to  the  subject  matter
herein and supersedes all prior or contemporaneous agreements whether written or oral.  This Agreement may
be modified only by agreement of the parties by a written instrument executed by the parties that is designated
as an amendment to this Agreement.

17.  Waiver of Breach.  The waiver of a breach of any term or provision of this Agreement, which must
be in writing, will not operate as or be construed to be a waiver of any other previous or subsequent breach of
this Agreement.

10

 
18.  Headings.   All  captions  and  section  headings  used  in  this Agreement  are  for  convenient  reference

only and do not form a part of this Agreement.

19.   Governing  Law.    This  Agreement  will  be  governed  by  the  laws  of  the  Commonwealth  of

Pennsylvania.

20.  Acknowledgment.    Executive  acknowledges  that  he  has  had  the  opportunity  to  discuss  this  matter
with and obtain advice from Executive’s private attorney, has had sufficient time to, and has carefully read and
fully  understands  all  the  provisions  of  this  Agreement,  and  is  knowingly  and  voluntarily  entering  into  this
Agreement.

21.  Counterparts.  This Agreement may be executed in counterparts, and each counterpart will have the

same force and effect as an original and will constitute an effective, binding agreement on the part of each of the
undersigned.

by their duly authorized officers, as of the day and year first above written.

Release and Waiver

TO BE SIGNED ON OR FOLLOWING THE SEPARATION DATE ONLY

    In  consideration  of  the  payments  and  other  benefits  set  forth  in  the  Employment  Agreement  of
(_________),  to  which  this  form  is  attached,  I, (_________),  hereby  furnish  Trevena,  Inc. (the “Company”),
with the following release and waiver of claims (“Release and Waiver”).

 In exchange for the consideration provided to me by the Employment Agreement that I am not otherwise
entitled to receive, I hereby generally and completely release the Company and its current and former directors,
officers,  employees,  stockholders,  partners,  agents,  attorneys,  predecessors,  successors,  parent  and  subsidiary
entities, insurers, affiliates, and assigns (collectively, the “Released Parties”) from any and all claims, liabilities
and obligations, both known and unknown, that arise out of or are in any way related to events, acts, conduct, or
omissions occurring prior to or on the date that I sign this Agreement (collectively, the “ Released Claims”).  The
Released  Claims  include,  but  are  not  limited  to:    (a)  all  claims  arising  out  of  or  in  any  way  related  to  my
employment with the Company, or the termination of that employment; (b) all claims related to my compensation
or  benefits  from  the  Company  including  salary,  bonuses,  commissions,  vacation  pay,  expense  reimbursements,
severance  pay,  fringe  benefits,  stock,  stock  options,  or  any  other  ownership  interests  in  the  Company;  (c)  all
claims  for  breach  of  contract,  wrongful  termination,  and  breach  of  the  implied  covenant  of  good  faith  and  fair
dealing; (d) all tort claims, including claims for fraud, defamation, emotional distress, and discharge in violation
of  public  policy;  and  (e)  all  federal,  state,  and  local  statutory  claims,  including  claims  for  discrimination,
harassment,  retaliation,  misclassification,  attorneys’  fees,  or  other  claims  arising  under  the  federal  Civil  Rights
Act of 1964 (as amended), the federal Americans with Disabilities Act of 1990, the federal Age Discrimination in
Employment Act of 1967 (as amended) (the “ADEA”), any other federal, state or local civil or human rights law
or  any  other  local,  state  or  federal  law,  regulation  or  ordinance,  including,  but  not  limited  to,  the  State  of
Pennsylvania or any subdivision thereof; and any public policy, contract, tort, or common law.  I hereby represent
and warrant that, other than the Excluded Claims, I am not aware of any claims I have or might have against any
of the Released Parties that are not included in the Released Claims. 

    In  granting  the  release  herein,  which  includes  claims  that  may  be  unknown  to  me  at  present,  I
acknowledge  that  I  expressly  waive  and  relinquish  any  and  all  rights  and  benefits  under  any  applicable  law  or
statute providing, in substance, that a general release does not extend to claims which a party does not know or
suspect to exist in his or her favor at the time of executing the release, which if known by him or her would have
materially affected the terms of such release. 

I acknowledge that, among other rights, I am waiving and releasing any rights I may have under ADEA,
that  this  Release  and  Waiver  is  knowing  and  voluntary,  and  that  the  consideration  given  for  this  Release  and
Waiver is in addition to anything of value to which I was already entitled as an executive of the Company.  If I am
40  years  of  age  or  older  upon  execution  of  this  Release  and  Waiver,  I  further  acknowledge  that  I  have  been
advised, as required by the Older Workers Benefit Protection Act, that:  (a) the release and waiver granted herein
does not relate to claims under the ADEA which may arise after this Release and Waiver is executed; (b) I should
consult with an attorney prior to executing this Release and Waiver; and (c) I have twenty-one (21) days from the
date of termination

13

 
 
of  my  employment  with  the  Company  in  which  to  consider  this  Release  and  Waiver  (although  I  may  choose
voluntarily to execute this Release and Waiver earlier); (d) I have seven (7) days following the execution of this
Release and Waiver to revoke my consent to this Release and Waiver; and (e) this Release and Waiver shall not
be  effective  until  the  seven  (7)  day  revocation  period  has  expired  without  my  having  previously  revoked  this
Release and Waiver.

 I  acknowledge  my  continuing  obligations  under  my Employee  Proprietary  Information,  Inventions  and
Non-Solicitation Agreement (the “PIIA”).  Pursuant to the PIIA I understand that among other things, I must not
use  or  disclose  any  confidential  or  proprietary  information  of  the  Company  and  I  must  immediately  return  all
Company property and documents (including all embodiments of proprietary information) and all copies thereof
in  my  possession  or  control.    I  understand  and  agree  that  my  right  to  the  severance  benefits  I  am  receiving  in
exchange for my agreement to the terms of this Release and Waiver is contingent upon my continued compliance
with my PIIA.

 This Release and Waiver constitutes the complete, final and exclusive embodiment of the entire

agreement between the Company and me with regard to the subject matter hereof.  I am not relying on any
promise or representation by the Company that is not expressly stated herein.  This Release and Waiver may only
be modified by a writing signed by both me and a duly authorized officer of the Company.

TREVENA, INC.

EMPLOYEE EMPLOYMENT AGREEMENT

This  Agreement  is  entered  as  of  May  14,  2018  by  and  between  Trevena,  Inc.  (the  “Company”),  a

Delaware corporation, and Robert Yoder.

WHEREAS, the Company desires to employ Employee to provide personal services to the Company, and
Employee wishes to be employed by the Company and provide personal services to the Company in return for
certain compensation and benefits.

Accordingly, in consideration of the mutual promises and covenants contained herein, the parties agree to

the following:

1.

 Duties and Scope of Employment.  

(a)

 Positions and Duties.  Effective as of June 4, 2018, Employee will serve as Vice
President, Sales and Commercial Operations of the Company.  Employee will render such business and
professional services in the performance of Employee’s duties, consistent with Employee’s position within the
Company, as will reasonably be assigned to Employee by the Company’s Executive Vice President and Chief
Operating Officer, to whom Employee will report.  The period of Employee’s employment under this Agreement
is referred to herein as the “Employment Term.” 

(b)

 Obligations.  During the Employment Term, Employee will perform
Employee’s  duties  faithfully  and  to  the  best  of  Employee’s  ability  and  will  devote  Employee’s  full  business
efforts  and  time  to  the  Company.    For  the  duration  of  the  Employment  Term,  Employee  agrees  not  to  actively
engage in any other employment, occupation or consulting activity for any direct or indirect remuneration without
the  prior  approval  of  the  Company’s  Chief  Executive  Officer.    Nothing  in  this Agreement  or  elsewhere  shall
prevent  Employee  from  managing  his  personal  investment  and  affairs,  or  from  engaging  in  charitable  and
community  affairs,  so  long  as  such  activities  do  not  either  individually  or  in  the  aggregate  interfere  with  the
performance of his duties for the Company.

2.

 At-Will Employment.  The parties agree that Employee’s employment with the Company will be
“at-will” employment and may be terminated at any time with or without cause or notice.  Employee’s at-will
employment  status  may  not  be  changed  except  by  way  of  written  agreement  signed  by  Employee  and  an
authorized officer of the Company.   

3.

 Compensation.  

(a)

 Base Salary.  During the Employment Term, the Company will pay Employee

an  initial  annualized  salary  of  $310,000  as  compensation  for  services.    The  Base  Salary  shall  be  paid  in  equal
installments in accordance with the Company’s normal payroll practices and subject to required withholding and
deductions.  The Base Salary will be subject to review and adjustments will be made based upon the Company’s
normal performance review practices.

 
 
DocuSign Envelope ID: 9AC8A669-45E5-4640-99C9-183FAE9E4266

(b)

 Bonus.  Subject to the terms and conditions set forth in the Trevena, Inc. Incentive
Compensation Plan (the “Plan”), Employee may be eligible to receive an annual bonus in a target amount of
30% of the Base Salary, subject to, among other things, the achievement of corporate and individual
performance objectives that will be established and assessed by the Company (the “Target Bonus”).  For 2018,
such individual objectives will be established within the first thirty (30) days after the Effective Date.  For each
subsequent calendar year, these individual objectives generally will be established within 90 days after the start
of such calendar year.  For 2018, Employee shall be eligible for the full year bonus target based on the company
performance factor, subject to the terms and conditions of the Plan.  The Company reserves the right to modify
the terms of the Plan, the Target Bonus and other components of bonus compensation and criteria from year to
year. 

(i)  Equity Award.  Upon the approval of the Company’s Board of

Directors or its designee, you will be granted an option to purchase 47,500 shares of the Company’s Common
Stock (as adjusted for stock splits, combinations, recapitalizations and the like after the date of this letter) at a
strike price and with vesting terms to be determined by the Company’s Board of Directors.  The stock option will
be subject to the terms and conditions applicable to options granted under the Company’s 2013 Equity Incentive
Plan, as amended, and the applicable option grant agreement.  At the time of annual performance reviews, you
may be considered for additional equity awards.  The purchase and sale of Trevena common stock (including the
exercise and sale of
Company stock options) will be subject to the Company’s Insider Trading and Window Period Policy. 

Company  Policies  and  Employee  Benefits.    During  the  Employment  Term,  Employee  will  be  eligible  to
participate  in  the  employee  benefit  plans  currently  and  hereafter  maintained  by  the  Company  of  general
applicability to other senior employees of the Company, including, without limitation, any such group medical,
dental,  vision,  disability,  life  insurance,  and  flexible-spending  account  plans.    All  matters  of  eligibility  for
coverage  and  benefits  under  any  benefit  plan  shall  be  determined  in  accordance  with  the  provisions  of  such
plan.    The  Company  reserves  the  right  to  cancel  or  change  the  benefit  plans  and  programs  it  offers  to  its
employees at any time.  

4.

  Vacation.    While  employed  pursuant  to  this  Agreement,  Employee  shall  be  eligible  to  take

vacation subject to the Company’s vacation policy.  

5.

 Expenses.  The Company will reimburse Employee for reasonable travel, entertainment or other
expenses  incurred  by  Employee  in  the  furtherance  of  or  in  connection  with  the  performance  of  Employee’s
duties hereunder, in accordance with the Company’s expense reimbursement policy.

6.

  Termination  of  Employment.    The  provisions  of  this  Section  7  govern  the  amount  of
compensation or benefit, if any, to be provided to Employee upon termination of employment and do not affect
the right of either party to terminate the employment relationship at any time for any reason.  

 Termination for other than Cause, Death or Disability.  If at any time (x) the
Company terminates Employee’s employment with the Company other than for Cause (as defined below), death
or disability, or (y) Employee terminates his employment under this Agreement for

Good Reason, then, subject to Section 8, Employee will be entitled to receive, less applicable withholdings and
deductions: 

the

(i)
 an amount equal to six (6) months of his annualized Base Salary in effect at the time of
termination,  payable  in  equal  installments  on  the  Company’s  regularly  scheduled  payroll  dates
beginning with the first payroll date following the effective date of the Release and Waiver;

(ii)
  (A)  a  pro-rata  bonus  for  the  calendar  year  of  termination,  determined  by  multiplying
Employee’s Target Bonus for such year (assuming employment for the entire year) by a fraction
whose numerator is the number of days that Employee was employed during such year and whose
denominator is the total number of days in such year, payable within 60 days following the date
of Employee’s termination of employment;  

(B)  to the extent not already paid, a cash incentive award under

Company’s Incentive Compensation Plan or any similar incentive plan (the “ICP”) related to the
fiscal year immediately preceding the year of termination in an amount as determined by the Board
or the Compensation Committee, as the case may be, in its sole judgment and discretion; 

(iii)
  if  Employee  timely  elects  continued  coverage  under  COBRA  for  Employee  and
Employee’s  covered  dependents  under  the  Company’s  group  health  plans  following  such
termination of employment, the Company will pay the COBRA premiums necessary to continue
Employee’s health insurance coverage in effect for Employee and Employee’s eligible dependents
on  the  termination  date,  as  and  when  due  to  the  insurance  carrier  or  COBRA  administrator  (as
applicable), until the earliest of (A) six (6) months from the effective date of such termination, (B)
the expiration of Employee’s eligibility for the continuation coverage under COBRA, or (C) the
date  when  Employee  becomes  eligible  for  substantially  equivalent  health  insurance  coverage  in
connection  with  new  employment  or  self-employment  (such  period  from  the  termination  date
through  the  earliest  of  (A)  through  (C),  the  “COBRA  Payment  Period”).  Notwithstanding  the
foregoing, if at any time the Company determines, in its sole discretion, that the payment of the
COBRA premiums would result in a violation of the nondiscrimination rules of Section 105(h)(2)
of  the  Code  or  any  statute  or  regulation  of  similar  effect  (including  but  not  limited  to  the  2010
Patient Protection and Affordable Care Act, as amended by the 2010 Health Care and Education
Reconciliation Act), then in lieu of providing the COBRA premiums, the Company will instead
pay Employee on the last day of each remaining month of the COBRA Payment Period, a fully
taxable  cash  payment  equal  to  the  COBRA  premiums  for  that  month,  subject  to  applicable  tax
withholdings  (such  amount,  the  “Special  Severance  Payment”),  for  the  remainder  of  the
COBRA Payment Period;

 and

(iv)
  accelerated  vesting  as  to  that  number  of  unvested  shares  subject  to    any  outstanding
equity awards held by Employee at the time of termination that would have otherwise vested if
Employee had remained a Company employee for six (6) months following the termination date.

(b)

 Termination In Connection With or Following a Change of Control.    In the

event that either (x) the Company terminates Employee’s employment with the Company other than for Cause,
death  or  disability  (A)  within  the  thirty  (30)  day  period  prior  to  a  Change  of  Control,  or  (B)  within  the  period
between the Company’s execution of a letter of intent for a proposed Change of Control which proposed Change
of Control is later consummated (a “Designated Change of Control”) and the consummation of such Designated
Change of Control, or (C) within the twelve (12) month period after a Change of Control, or (y) Employee resigns
for Good Reason within twelve (12) months after a Change of Control, then, in addition to the payments set forth
in  Section  7(a)  above,  and  subject  to  Section  8  below,  Employee  shall  also  be  entitled  to,  less  applicable
withholdings and deductions: 

(i)
 an amount equal to nine (9) months of Employee’s annualized Base Salary in effect at the
time of termination, payable in equal installments on the Company’s regularly scheduled payroll
dates beginning with the first payroll date following the effective date of the Release and Waiver;

(ii)
  (A)  a  pro-rata  bonus  for  the  calendar  year  of  termination,  determined  by  multiplying
Employee’s Target Bonus for such year (assuming employment for the entire year) by a fraction
whose numerator is the number of days that Employee was employed during such year and whose
denominator is the total number of days in such year, payable within 60 days following the date
of Employee’s termination of employment;  

(B) to the extent not already paid, a cash incentive award under the ICP related to the fiscal
year immediately preceding the year of termination in an amount as determined by the Board or the
Compensation Committee, as the case may be, in its sole judgment and discretion; 

(iii)
 an amount equal to 75% of Employee’s Target Bonus in effect at the time of termination,
payable in equal installments on the Company’s regularly scheduled payroll dates beginning with
the first payroll date following the effective date of the Release and Waiver;

(iv)
  if  Employee  timely  elects  continued  coverage  under  COBRA  for  Employee  and
Employee’s  covered  dependents  under  the  Company’s  group  health  plans  following  such
termination of employment, the Company will pay the COBRA premiums necessary to continue
Employee’s health insurance coverage in effect for Employee and Employee’s eligible dependents
on  the  termination  date,  as  and  when  due  to  the  insurance  carrier  or  COBRA  administrator  (as
applicable), until the earliest of (A) nine (9) months from the effective date of such termination,
(B) the expiration of

4 

 
 
 
DocuSign Envelope ID: 9AC8A669-45E5-4640-99C9-183FAE9E4266

Employee’s  eligibility  for  the  continuation  coverage  under  COBRA,  or  (C)  the  date  when
Employee  becomes  eligible  for  substantially  equivalent  health  insurance  coverage  in  connection
with  new  employment  or  self-employment  (such  period  from  the  termination  date  through  the
earliest of (A) through (C), the “COBRA Payment Period”). Notwithstanding the foregoing, if at
any  time  the  Company  determines,  in  its  sole  discretion,  that  the  payment  of  the  COBRA
premiums  would  result  in  a  violation  of  the  nondiscrimination  rules  of  Section  105(h)(2)  of  the
Code  or  any  statute  or  regulation  of  similar  effect  (including  but  not  limited  to  the  2010  Patient
Protection  and  Affordable  Care  Act,  as  amended  by  the  2010  Health  Care  and  Education
Reconciliation Act),  then  in  lieu  of  providing  the  COBRA  premiums,  the  Company  will  instead
pay  Employee  on  the  last  day  of  each  remaining  month  of  the  COBRA  Payment  Period,  a  fully
taxable  cash  payment  equal  to  the  COBRA  premiums  for  that  month,  subject  to  applicable  tax
withholdings (such amount, the “Special Severance

Payment”), for the remainder of the COBRA Payment Period; and
(v)
 immediate and full accelerated vesting of all unvested shares subject to any outstanding
equity  awards  held  by  Employee  at  the  time  of  termination; provided,   however,  that  such
acceleration  shall  not  be  interpreted  to  extend  the  post-termination  exercise  period  of  any  stock
option held by Employee at the time of termination, unless otherwise approved by the Board.

(c)

  Termination  for  Cause,  Death  or  Disability;  Voluntary  Termination .    If  Employee’s
employment with the Company terminates voluntarily by Employee (other than for Good Reason as set forth in
the preceding subsection (b)), for Cause by the Company or due to Employee’s death or disability, then (i) all
vesting will terminate immediately with respect to Employee’s outstanding equity awards, (ii) all payments of
compensation by the Company to Employee hereunder will terminate immediately (except as to amounts already
earned).

 Termination by Mutual Consent.  If at any time during the course of this Agreement the
parties  by  mutual  consent  decide  to  terminate  this Agreement,  they  shall  do  so  by  separate  agreement  setting
forth the terms and condition of such termination.

(d)

 Conditions to Receipt of Benefits under Section 7.  

(a)

 Release of Claims.  The receipt of any payment or benefit pursuant to Section 7

will  be  subject  to  Employee  signing  and  not  revoking  a  release  and  waiver  of  all  claims  in  the  form  attached
hereto  as Exhibit A  (or in such other form as may be specified by the Company in order to comply with then-
existing legal requirements to effect a valid release of claims) (the “Release and Waiver”) within the applicable
time period set forth therein, but in no event later than forty-five days following termination of employment.  No
payment  or  benefit  pursuant  to  Section  7  will  be  paid  or  provided  until  the  Release  and  Waiver  becomes
effective.

(b)

 Other Conditions.  The receipt of any payment or benefits pursuant to Section 7

will  be  subject  to  Employee  not  violating  the  PIIA  (as  defined  below),  returning  all  Company  property,  and
complying  with  the  Release  and  Waiver;  provided,  however,  that  Company  must  provide  written  notice  to
Employee of the condition under this Section 8(b) that could prevent the disbursement of any payment or benefits
under Section (7) within thirty (30) days of the initial existence of such condition and such condition must not
have  been  remedied  by  Employee  within  thirty  (30)  days  of  such  written  notice.    Employee  understands  and
agrees that payment or benefits received pursuant to Section 7 are in lieu of and not in addition to any severance or
similar benefits that may be provided to other employees of the Company pursuant to a Company policy or plan.

(c)

 Section 409A.  Notwithstanding anything to the contrary set forth herein, any

payments  and  benefits  provided  under  Section  7  above  that  constitute  “deferred  compensation”  within  the
meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”)  and  the  regulations
and  other  guidance  thereunder  and  any  state  law  of  similar  effect  (collectively “Section  409A”)  shall  not
commence  in  connection  with  Employee’s  termination  of  employment  unless  and  until  Employee  has  also
incurred  a  “separation  from  service”  (as  such  term  is  defined  in  Treasury  Regulation  Section  1.409A-1(h)
(“Separation From Service”), unless the Company reasonably determines that such amounts may be provided to
Employee  without  causing  Employee  to  incur  the  additional  20%  tax  under  Section  409A.    Pay  pursuant  to
Section 7 above, to the extent of payments made from the date of termination of Employee’s employment through
March  15  of  the  calendar  year  following  such  termination,  are  intended  to  constitute  separate  payments  for
purposes of Section
1.409A-2(b)(2) of the Treasury Regulations and thus payable pursuant to the “short-term deferral” rule set forth in
Section 1.409A-1(b)(4) of the Treasury Regulations; to the extent such payments are made following said March
15,  they  are  intended  to  constitute  separate  payments  for  purposes  of  Section  1.409A-2(b)(2)  of  the  Treasury
Regulations made upon an involuntary termination of service and payable pursuant to Section 1.409A-1(b)(9)(iii)
of the Treasury Regulations, to the maximum extent permitted by said provision, with any excess amount being
regarded  as  subject  to  the  distribution  requirements  of  Section  409A(a)(2)(A)  of  the  Internal  Revenue  Code,
including,  without  limitation,  the  requirement  of  Section  409A(a)(2)(B)(i)  of  the  Code  that,  if    Employee  is  a
“specified  employee”  within  the  meaning  of  the  aforesaid  Section  of  the  Code  at  the  time  of  such  termination
from  employment,  payments  be  delayed  until  the  earlier  of  six  months  after  termination  of  employment  or
Employee’s  death  (such  applicable  date,  the “Specified  Employee  Initial  Payment  Date”).    Notwithstanding
any other payment schedule set forth in herein, none of the payments under Section 7 will be paid or otherwise
delivered  prior  to  the  effective  date  of  the  Release  and  Waiver.    Except  to  the  extent  that  payments  may  be
delayed until the Specified Employee Initial Payment Date pursuant to the preceding sentence, on the first regular
payroll  pay  day  following  the  effective  date  of  the  Release  and  Waiver,  the  Company  will  pay  Employee  the
payments Employee would otherwise have received under Section 7 on or prior to such date but for the delay in
payment related to the effectiveness of the Release and Waiver, with the balance of the payments being paid as
originally scheduled.  Notwithstanding anything to the contrary set forth herein, if any of the payments or benefits
set forth in Section 7 constitute “deferred compensation” within the meaning of Section 409A of the Code and the
period during which Employee may review, execute and revoke the Release and Waiver

begins in one taxable year and ends in a second taxable year, such payments and benefits shall commence or be
made in the second taxable year.

(d)

 Cooperation With the Company After Termination of Employment. Following

termination of the Employee’s employment for any reason, upon request by the Company, Employee will fully
cooperate  with  the  Company  (at  the  Company’s  reasonable  expense)  in  all  matters  reasonably  relating  to  the
winding up of pending work including, but not limited to, any litigation in which the Company is involved, and
the orderly transfer of any such pending work to such other employees as may be designated by the Company.

nominated for election, to the Board with the affirmative votes of at least a majority of the Incumbent Directors at
the  time  of  such  election  or  nomination  (but  will  not  include  an  individual  whose  election  or  nomination  is  in
connection  with  an  actual  or  threatened  proxy  contest  relating  to  the  election  of  directors  to  the  Company);

such written notice (the “Cure Period”).                

9.

Proprietary  Information,  Inventions  and  Non-Solicitation  Agreement  (the  “PIIA”),  in  substantially  the  form
attached hereto as EXHIBIT B, upon commencing employment hereunder.  

10.

  No  Conflict  with  Existing  Obligations.    Employee  represents  that  his  performance  of  all  the
terms of this Agreement and, as an Employee officer of the Company, do not and will not breach any agreement
or  obligation  of  any  kind  made  prior  to  Employee’s  employment  by  the  Company,  including  agreements  or

services.  Employee has not entered into, and Employee agrees that Employee will not enter into, any agreement

11.

 Parachute Payments. 

(a)

 If any payment or benefit Employee would receive pursuant to a Change of

Control  from  the  Company  or  otherwise  (“Payment”)  would  (i)  constitute  a  “parachute  payment”  within  the
meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), and (ii) but for this
sentence,  be  subject  to  the  excise  tax  imposed  by  Section  4999  of  the  Code  (the  “Excise  Tax ”),  then  such
Payment shall be reduced to the Reduced Amount.  The “Reduced Amount” shall be either (x) the largest portion
of the Payment that would result in no portion of the Payment

8 

 
 
 
 
DocuSign Envelope ID: 9AC8A669-45E5-4640-99C9-183FAE9E4266

being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment, whichever
amount, after taking into account all applicable federal, state and local employment taxes, income taxes, and the
Excise Tax (all computed at the highest applicable marginal rate), results in Employee’s receipt, on an after-tax
basis,  of  the  greater  amount  of  the  Payment  notwithstanding  that  all  or  some  portion  of  the  Payment  may  be
subject to the Excise Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so
that the Payment equals the Reduced Amount, reduction shall occur in the following order unless Employee elects
in writing a different order (provided, however,  that such election shall be subject to Company approval if made
on  or  after  the  date  on  which  the  event  that  triggers  the  Payment  occurs):    reduction  of  cash  payments;
cancellation of accelerated vesting of stock awards; reduction of employee benefits.  In the event that acceleration
of  vesting  of  stock  award  compensation  is  to  be  reduced,  such  acceleration  of  vesting  shall  be  cancelled  in  the
reverse order of the date of grant of Employee’s stock awards unless Employee elects in writing a different order
for cancellation.

(b)

 The accounting firm engaged by the Company for general audit purposes as of

the  day  prior  to  the  effective  date  of  the  Change  of  Control  shall  perform  the  foregoing  calculations.    If  the
accounting firm so engaged by the Company is serving as accountant or auditor for the individual, entity or group
affecting the Change of Control, the Company shall appoint a nationally recognized accounting firm to make the
determinations required hereunder.  The Company shall bear all expenses with respect to the determinations by
such  accounting  firm  required  to  be  made  hereunder.  (c) 
The  accounting  firm  engaged  to  make  the
determinations hereunder shall
provide its calculations, together with detailed supporting documentation, to the Company and Employee within
fifteen (15) calendar days after the date on which Employee’s right to a Payment is triggered (if requested at that
time  by  the  Company  or  Employee)  or  such  other  time  as  requested  by  the  Company  or  Employee.    If  the
accounting firm determines that no Excise Tax is payable with respect to a Payment, it shall furnish the Company
and  Employee  with  an  opinion  reasonably  acceptable  to  Employee  that  no  Excise  Tax  will  be  imposed  with
respect to such Payment.  Any good faith determinations of the accounting firm made hereunder shall be final,
binding and conclusive upon the Company and Employee.  

12.

  Assignment.    This Agreement  will  be  binding  upon  and  inure  to  the  benefit  of  (a)  the  heirs,
executors  and  legal  representatives  of  Employee  upon  Employee’s  death  and  (b)  any  successor  of  the
Company.  Any such successor of the Company will be deemed substituted for the Company under the terms of
this Agreement  for  all  purposes.    For  this  purpose,  “successor”  means  any  person,  firm,  corporation  or  other
business entity which at any time, whether by purchase, merger or otherwise, directly or indirectly acquires all or
substantially all of the assets or business of the Company.  None of the rights of Employee to receive any form
of compensation payable pursuant to this Agreement may be assigned or transferred except by will or the laws of
descent  and  distribution.    Any  other  attempted  assignment,  transfer,  conveyance  or  other  disposition  of
Employee’s right to compensation or other benefits will be null and void.

13.

 Notices.  All notices, requests, demands and other communications called for hereunder will be
in  writing  and  will  be  deemed  given  (i)  on  the  date  of  delivery  if  delivered  personally,  (ii)  one  (1)  day  after
being sent by a nationally recognized commercial overnight service, specifying next day delivery, with written
verification of receipt, or (iii) four (4) days after being mailed by registered or

14.

 Severability.  In the event that any provision of this Agreement becomes or is declared by a court
of  competent  jurisdiction  to  be  illegal,  unenforceable  or  void,  this Agreement  will  continue  in  full  force  and
effect without said provision.

15.

 Arbitration.  

(a)

 Arbitration.  In consideration of Employee’s employment with the Company,

the Company and Employee agree that any and all controversies, claims, or disputes with anyone (including the
Company and any employee, officer, director, shareholder or benefit plan of the
Company  in  their  capacity  as  such  or  otherwise)  arising  out  of,  relating  to,  or  resulting  from  Employee’s
employment with the Company or the termination of Employee’s employment with the Company, including any
breach of this Agreement, but not including those arising out of, relating to, or resulting from the PIAA, will  be
subject to binding arbitration.  Disputes which Employee agrees to arbitrate, and thereby agrees to waive any right
to a trial by jury, include any statutory claims under state or federal law, including, but not limited to, claims under
Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act of 1990, the Age Discrimination in
Employment  Act  of  1967,  the  Older  Workers  Benefit  Protection  Act,  the  Worker  Adjustment  and  Retraining
Notification Act,  the  Family  and  Medical  Leave Act,  discrimination  or  wrongful  termination  and  any  statutory
claims.    Employee  further  understands  that  this  Agreement  to  arbitrate  also  applies  to  any  disputes  that  the
Company may have with Employee.

(b)

 Procedure.  Employee agrees that any arbitration will be administered by the American
Arbitration Association (“AAA”) and that the neutral arbitrator will be selected in a manner consistent with its
National Rules for the Resolution of Employment Disputes (“the Rules”).  Employee agrees that the arbitrator
will administer and conduct any arbitration in a manner consistent with the Rules.

(c)

 Remedy.  Except as provided by this Agreement and by the Rules, including

any  provisional  relief  offered  therein,  arbitration  will  be  the  sole,  exclusive  and  final  remedy  for  any  dispute
between  Employee  and  the  Company.   Accordingly,  except  as  provided  for  by  the  Rules  and  this Agreement,
neither Employee nor the Company will be permitted to pursue court action regarding claims that are subject to
arbitration.  

(d)

 Administrative Relief.  Employee understands that this Agreement does not

prohibit Employee from pursuing an administrative claim with a local, state or federal administrative body such as
the Equal Employment Opportunity Commission or the workers’ compensation board. 

10 

 
 
DocuSign Envelope ID: 9AC8A669-45E5-4640-99C9-183FAE9E4266

This Agreement does, however, preclude Employee from pursuing court action regarding any such claim.

(e)

 Voluntary Nature of Agreement .  Employee acknowledges and agrees that Employee is
executing  this Agreement  voluntarily  and  without  any  duress  or  undue  influence  by  the  Company  or  anyone
else.    Employee  further  acknowledges  and  agrees  that  Employee  has  carefully  read  this Agreement  and  that
Employee  has  asked  any  questions  needed  for  Employee  to  understand  the  terms,  consequences  and  binding
effect of this Agreement and fully understands it, including that  Employee is waiving Employee’s right to a jury
trial.    Finally,  Employee  agrees  that  Employee  has  been  provided  an  opportunity  to  seek  the  advice  of  an
attorney of Employee’s choice before signing this Agreement.

16.

 Integration.  This Agreement, together with the PIIA and the other documents referred to in this
Agreement,  represents  the  entire  agreement  and  understanding  between  the  parties  as  to  the  subject  matter
herein and supersedes all prior or contemporaneous agreements whether written or oral.  This Agreement may be
modified only by agreement of the parties by a written instrument executed by the parties that is designated as
an amendment to this Agreement.

17.

 Waiver of Breach.  The waiver of a breach of any term or provision of this Agreement, which
must be in writing, will not operate as or be construed to be a waiver of any other previous or subsequent breach
of this Agreement.

18.

 Headings.  All captions and section headings used in this Agreement are for convenient reference

only and do not form a part of this Agreement.

  Governing  Law.    This  Agreement  will  be  governed  by  the  laws  of  the  Commonwealth  of

  Acknowledgment.    Employee  acknowledges  that  he  has  had  the  opportunity  to  discuss  this
matter  with  and  obtain  advice  from  Employee’s  private  attorney,  has  had  sufficient  time  to,  and  has  carefully
read and fully understands all the provisions of this Agreement, and is knowingly and voluntarily entering into
this Agreement.

TO BE SIGNED ON OR FOLLOWING THE SEPARATION DATE ONLY

In  consideration  of  the  payments  and  other  benefits  set  forth  in  the  Employment  Agreement  of
[_________], to which this form is attached, I, [_________], hereby furnish TREVENA,  INC.  (the “Company”),
with the following release and waiver of claims (“Release and Waiver”). 

In exchange for the consideration provided to me by the Employment Agreement that I am not otherwise
entitled to receive, I hereby generally and completely release the Company and its current and former directors,
officers,  employees,  stockholders,  partners,  agents,  attorneys,  predecessors,  successors,  parent  and  subsidiary
entities, insurers, affiliates, and assigns (collectively, the “Released Parties”) from any and all claims, liabilities
and obligations, both known and unknown, that arise out of or are in any way related to events, acts, conduct, or
omissions occurring prior to or on the date that I sign this Agreement (collectively, the “ Released Claims”).  The
Released  Claims  include,  but  are  not  limited  to:    (a)  all  claims  arising  out  of  or  in  any  way  related  to  my
employment with the Company, or the termination of that employment; (b) all claims related to my compensation
or  benefits  from  the  Company  including  salary,  bonuses,  commissions,  vacation  pay,  expense  reimbursements,
severance  pay,  fringe  benefits,  stock,  stock  options,  or  any  other  ownership  interests  in  the  Company;  (c)  all
claims  for  breach  of  contract,  wrongful  termination,  and  breach  of  the  implied  covenant  of  good  faith  and  fair
dealing; (d) all tort claims, including claims for fraud, defamation, emotional distress, and discharge in violation
of  public  policy;  and  (e)  all  federal,  state,  and  local  statutory  claims,  including  claims  for  discrimination,
harassment,  retaliation,  misclassification,  attorneys’  fees,  or  other  claims  arising  under  the  federal  Civil  Rights
Act of 1964 (as amended), the federal Americans with Disabilities Act of 1990, the federal Age Discrimination in
Employment Act of 1967 (as amended) (the “ADEA”), any other federal, state or local civil or human rights law
or  any  other  local,  state  or  federal  law,  regulation  or  ordinance,  including,  but  not  limited  to,  the  State  of
Pennsylvania or any subdivision thereof; and any public policy, contract, tort, or common law.  I hereby represent
and warrant that, other than the Excluded Claims, I am not aware of any claims I have or might have against any
of the Released Parties that are not included in the Released Claims. 

In  granting  the  release  herein,  which  includes  claims  that  may  be  unknown  to  me  at  present,  I
acknowledge  that  I  expressly  waive  and  relinquish  any  and  all  rights  and  benefits  under  any  applicable  law  or
statute providing, in substance, that a general release does not extend to claims which a party does not know or
suspect to exist in his or her favor at the time of executing the release, which if known by him or her would have
materially affected the terms of such release.  

I acknowledge that, among other rights, I am waiving and releasing any rights I may have under ADEA,
that  this  Release  and  Waiver  is  knowing  and  voluntary,  and  that  the  consideration  given  for  this  Release  and
Waiver is in addition to anything of value to which I was already entitled as an employee of the Company.  If I am
40  years  of  age  or  older  upon  execution  of  this  Release  and  Waiver,  I  further  acknowledge  that  I  have  been
advised, as required by the Older Workers Benefit Protection

Act, that:  (a) the release and waiver granted herein does not relate to claims under the ADEA which may arise
after this Release and Waiver is executed; (b) I should consult with an attorney prior to executing this Release and
Waiver; and (c) I have twenty-one (21) days from the date of termination of my employment with the Company in
which to consider this Release and Waiver (although I may choose voluntarily to execute this Release and Waiver
earlier); (d) I have seven (7) days following the execution of this Release and Waiver to revoke my consent to this
Release  and  Waiver;  and  (e)  this  Release  and  Waiver  shall  not  be  effective  until  the  seven  (7)  day  revocation
period has expired without my having previously revoked this Release and Waiver.

I acknowledge my continuing obligations under my Employee Proprietary Information,
Inventions  and  Non-Solicitation Agreement  (the  “ PIIA”).    Pursuant  to  the  PIIA  I  understand  that  among  other
things,  I  must  not  use  or  disclose  any  confidential  or  proprietary  information  of  the  Company  and  I  must
immediately return all Company property and documents (including all embodiments of proprietary information)
and all copies thereof in my possession or control.  I understand and agree that my right to the severance benefits I
am  receiving  in  exchange  for  my  agreement  to  the  terms  of  this  Release  and  Waiver  is  contingent  upon  my
continued compliance with my PIIA.

This Release and Waiver constitutes the complete, final and exclusive embodiment of the entire agreement

between the Company and me with regard to the subject matter hereof.  I am not relying on any promise or
representation by the Company that is not expressly stated herein.  This Release and Waiver may only be
modified by a writing signed by both me and a duly authorized officer of the Company.

writing.    I  will  obtain  the  Company’s  written  approval  before
publishing  or  submitting  for  publication  any  material  (written,  verbal,

1.5

  No  Improper  Use  of  Information  of  Prior
Employers and Others.  During my employment by the Company
I  will  not  improperly  use  or  disclose  any  confidential  information
or trade secrets, if any, of any former employer or any other person
to  whom  I  have  an  obligation  of  confidentiality,  and  I  will  not
bring  onto  the  premises  of  the  Company  any  unpublished
documents  or  any  property  belonging  to  any  former  employer  or
any  other  person  to  whom  I  have  an  obligation  of  confidentiality

 ASSIGNMENT OF INVENTIONS.  

2.1
term

P r o p r i e t a r y Rights. 

The

“Proprietary  Rights”  shall  mean  all 
trade  secrets,  patents,
copyrights, trade marks, mask works and other intellectual property
rights throughout the world. 

to 

2.2

to  practice  prior 

 Prior Inventions.    Inventions,  if  any,  patented
or  unpatented,  which  I  made  prior  to  the  commencement  of  my
employment with the Company are excluded from the scope of this
Agreement.  To preclude any possible uncertainty, I have set forth
on EXHIBIT   A  (Previous  Inventions)  attached  hereto  a  complete
list  of  all  Inventions  that  I  have,  alone  or  jointly  with  others,
conceived,  developed  or  reduced  to  practice  or  caused  to  be
conceived,  developed  or  reduced 
the
commencement  of  my  employment  with  the  Company,  that  I
consider to be my property or the property of third parties, and that
I  wish  to  have  excluded  from  the  scope  of  this  Agreement
(collectively  referred  to  as  “Prior  Inventions”).    If  disclosure  of
any  such  Prior  Invention  would  cause  me  to  violate  any  prior
confidentiality  agreement,  I  understand  that  I  am  not  to  list  such
Prior Inventions in EXHIBIT  A but am only to disclose a cursory
name for each such invention, a listing of the party(ies) to whom it
belongs  and  the  fact  that  full  disclosure  as  to  such  inventions  has
not been made for that reason. A space is provided on  EXHIBIT A
for such purpose.  If no such disclosure is attached, I represent that
there are no Prior Inventions.  If, in the course of my employment
with the Company, I incorporate a Prior Invention into a Company
product,  process  or  machine,  the  Company  is  hereby  granted  and
shall  have  a  nonexclusive,  royalty-free,  irrevocable,  perpetual,
fully-paid,  worldwide  license  (with  rights  to  sublicense  through
multiple tiers of sublicensees) to make, have made, modify, make
derivative  works  of,  publicly  perform,  publicly  perform,  use,  sell,
import,  and  exercise  any  and  all  present  and  future  rights  in  such
Prior Invention.  Notwithstanding the foregoing, I agree that I will
not  incorporate,  or  permit  to  be  incorporated,  Prior  Inventions  in
any  Company  Inventions  without  the  Company's  prior  written
consent.

2.3

  Subject 

  Assignment  of  Inventions. 

to
Subsections 2.4 and 2.6, I hereby assign and agree to assign in the
future  (when  any  such  Inventions  or  Proprietary  Rights  are  first
reduced  to  practice  or  first  fixed  in  a  tangible  medium,  as
applicable) to the Company all my right, title and interest in and to
any  and  all  Inventions  (and  all  Proprietary  Rights  with  respect
thereto) whether or not patentable or registrable under copyright or
similar statutes, made or conceived or reduced to practice or learned
by me, either alone or jointly with others, during the period of my
employment  with  the  Company.    Inventions  assigned  to  the
Company, or to a third party as directed by the Company pursuant
to  this  Section  2,  are  hereinafter  referred  to  as  “Company
Inventions.”  

2.4

 Unassigned  or  Nonassignable
Inventions.  I recognize that this Agreement will not be deemed to
require assignment of any Invention that I developed entirely on my
own  time  without  using  the  Company’s  equipment,  supplies,
facilities, trade secrets, or Proprietary Information, except for those
Inventions  that  either  (i)  relate  to  the  Company’s  actual  or
anticipated business, research or development, or (ii) result from or
are  connected  with  work  performed  by  me  for  the  Company.    In
addition,  this  Agreement  does  not  apply  to  any  Invention  which
qualifies fully for protection from assignment to the Company under
any  specifically  applicable  state  law,  regulation,  rule,  or  public
policy (“Specific Inventions Law”).

2.5

 Obligation  to  Keep  Company

 
 
 
 
 
1.4

 Term of Nondisclosure Restrictions.  I understand
that Proprietary Information and Third Party Information is never to be
used or disclosed by me, as provided in this Section 1.  If, however, a
court  decides  that  this  Section  1  or  any  of  its  provisions  is
unenforceable  for  lack  of  reasonable  temporal  limitation  and  the
Agreement  or  its  restriction(s)  cannot  otherwise  be  enforced,  I  agree
and the Company agrees that the two (2) year period after the date my
employment ends shall be the temporal limitation

Informed.    During  the  period  of  my  employment  and  for  six  (6)
months  after  termination  of  my  employment  with  the  Company,  I
will  promptly  disclose  to  the  Company  fully  and  in  writing  all
Inventions authored, conceived or reduced to practice by me, either
alone or jointly with others.   In addition, I will promptly disclose to
the  Company  all  patent  applications  filed  by  me  or  on  my  behalf
within a year after termination of employment.  At the time of each
such  disclosure,  I  will  advise  the  Company  in  writing  of  any
Inventions  that  I  believe  fully  qualify  for  protection  under  the
provisions  of  a  Specific  Inventions  Law;  and  I  will  at  that  time
provide  to  the  Company  in  writing  all  evidence  necessary  to
substantiate that belief.  The Company will keep in confidence and
will not use for any purpose or disclose to third parties without my
consent  any  confidential  information  disclosed  in  writing  to  the
Company  pursuant  to  this  Agreement  relating  to  Inventions  that
qualify fully for protection under a Specific Inventions Law.  I will
preserve  the  confidentiality  of  any  Invention  that  does  not  fully
qualify for protection under a Specific Inventions Law.

2.6

 Government  or  Third  Party.    I  also  agree  to
assign  all  my  right,  title  and  interest  in  and  to  any  particular
Company Invention to a third party, including

 
 
DocuSign Envelope ID: 9AC8A669-45E5-4640-99C9-183FAE9E4266

without limitation the United States, as directed by the Company.

2.7

  Works  for  Hire.     I  acknowledge  that  all  original
works  of  authorship  which  are  made  by  me  (solely  or  jointly  with
others) within the scope of my employment and which are protectable
by  copyright  are  “works  made  for  hire,”  pursuant  to  United  States
Copyright Act (17 U.S.C., Section 101).

2.8

 Enforcement  of  Proprietary  Rights.    I  will  assist
the  Company  in  every  proper  way  to  obtain,  and  from  time  to  time
enforce,  United  States  and  foreign  Proprietary  Rights  relating  to
Company  Inventions  in  any  and  all  countries.    To  that  end  I  will
execute, verify and deliver such documents and perform such other acts
(including  appearances  as  a  witness)  as  the  Company  may  reasonably
request  for  use  in  applying  for,  obtaining,  perfecting,  evidencing,
sustaining  and  enforcing  such  Proprietary  Rights  and  the  assignment
thereof.    In  addition,  I  will  execute,  verify  and  deliver  assignments  of
such Proprietary Rights to the Company or its designee.  My obligation
to assist the Company with respect to Proprietary Rights relating to such
Company Inventions in any and all countries shall continue beyond the
termination of my employment, but the Company shall compensate me
at a reasonable rate after my termination for the time actually spent by
me at the Company’s request on such assistance.

In  the  event  the  Company  is  unable  for  any  reason,  after  reasonable
effort,  to  secure  my  signature  on  any  document  needed  in  connection
with  the  actions  specified  in  the  preceding  paragraph,  I  hereby
irrevocably designate and appoint the Company and its duly authorized
officers and agents as my agent and attorney in fact, which appointment
is coupled with an interest, to act for and in my behalf to execute, verify
and file any such documents and to do all other lawfully permitted acts
to  further  the  purposes  of  the  preceding  paragraph  with  the  same  legal
force and effect as if executed by me.  I hereby waive and quitclaim to
the Company any and all claims, of any nature whatsoever, which I now
or  may  hereafter  have  for  infringement  of  any  Proprietary  Rights
assigned hereunder to the Company.

3.
 RECORDS.  I agree to keep and maintain adequate and current
records (in the form of notes, sketches, drawings and in any other form
that  may  be  required  by  the  Company)  of  all  Proprietary  Information
developed  by  me  and  all  Inventions  made  by  me  during  the  period  of
my  employment  at  the  Company,  which  records  shall  be  available  to
and remain the sole property of the Company at all times.

 DUTY  OF LOYALTY  DURING EMPLOYMENT.    I  agree  that
4.
during  the  period  of  my  employment  by  the  Company  I  will  not,
without  the  Company’s  express  written  consent,  directly  or  indirectly
engage  in  any  employment  or  business  activity  which  is  directly  or
indirectly  competitive  with,  or  would  otherwise  conflict  with,  my
employment by the Company.    

5.

NO  
EMPLOYEES, 

SO L I C I T A T I O N 

OF

CONSULTANTS, CONTRACTORS, OR CUSTOMERS OR
POTENTIAL CUSTOMERS.    
I  agree  that  during  the  period  of  my
employment  and  for  the  twelve  (12)  month  period  after  the  date  my
employment ends for any reason, including but not limited to voluntary
termination  by  me  or  involuntary  termination  by  the  Company,  I  will
not,  as  an  officer,  director,  employee,  consultant,  owner,  partner,  or  in
any other capacity, either directly or through others, except on behalf of
the Company:

5.1

 solicit, induce, encourage, or participate in soliciting,
inducing,  or  encouraging  any  employee  of  the  Company  to  terminate
his or her relationship with the Company;

 hire, employ, or engage in business with or attempt to
hire,  employ,  or  engage  in  business  with  any  person  employed  by  the
Company or who has left the employment  of  the  Company  within  the
preceding  three  (3)  months  or  discuss  any  potential  employment  or
business  association  with  such  person,  even  if  I  did  not  initiate  the
discussion or seek out the contact; or

5.3

 solicit, induce or attempt to induce any Customer or
Potential  Customer  (as  defined  below),  or  any  consultant  or
independent  contractor  with  whom  I  had  direct  or  indirect  contact  or
whose  identity  I  learned  as  a  result  of  my  employment  with  the
Company,  to  terminate,  diminish,  or  materially  alter  in  a  manner
harmful to the Company its relationship with the Company.

The  parties  agree  that  for  purposes  of  this Agreement,  a  “Customer  or
Potential Customer” is any person or entity who or which, at any time
during  the  one  (1)  year  prior  to  the  date  my  employment  with  the
Company  ends,  (i)  contracted  for,  was  billed  for,  or  received  from  the
Company any product, service or process with which I worked directly
or indirectly during my employment by the Company or about which I
acquired  Proprietary  Information;  or  (ii)  was  in  contact  with  me  or  in
contact  with  any  other  employee,  owner,  or  agent  of  the  Company,  of
which contact I was or should have been aware, concerning any product,
service or process with which I worked directly or indirectly during my
employment  with  the  Company  or  about  which  I  acquired  Proprietary
Information; or (iii) was solicited by the Company in an effort in which I
was involved or of which I was or should have been aware.

agree  that  I  am  entering  into  this  Agreement  freely  and  with
knowledge  of  its  contents  with  the  intent  to  be  bound  by  the
Agreement and the restrictions contained in it.

6.2

 In the event that a court finds this Agreement, or
any of its restrictions, to be ambiguous, unenforceable, or invalid, I
and the Company agree that the court shall read the Agreement as a
whole and interpret the restriction(s) at issue to be enforceable and
valid to the maximum extent allowed by law.

7.

  NO  
OR

CONFLICTING 

AGREEMENT

OBLIGATION.  I represent that my performance of all the terms of
this Agreement  and  as  an  employee  of  the  Company  does  not  and
will  not  breach  any  agreement  to  keep  in  confidence  information
acquired by me in confidence or in trust prior to my employment by
the Company.  I have not entered into, and I agree I will not enter
into, any agreement either written or oral in conflict herewith.

 RETURN  OF COMPANY PROPERTY.    When  I  leave  the
8.
employ of the Company, I will deliver to the Company any and all
drawings, notes, memoranda, specifications, devices, formulas, and
documents, together with all copies thereof, and any other material
containing  or  disclosing  any  Company  Inventions,  Third  Party
Information or Proprietary Information of the Company.  I further
agree  that  any  property  situated  on  the  Company’s  premises  and
owned  by  the  Company,  including  disks  and  other  storage  media,
filing  cabinets  or  other  work  areas,  is  subject  to  inspection  by
Company  personnel  at  any  time  with  or  without  notice.    Prior  to
leaving,  I  will  cooperate  with  the  Company  in  completing  and
signing the Company’s termination statement if requested to do so
by the Company.

9.

 LEGAL AND EQUITABLE REMEDIES.  

9.1

 I  agree  that  it  may  be  impossible  to  assess  the
damages  caused  by  my  violation  of  this Agreement  or  any  of  its
terms.    I  agree  that  any  threatened  or  actual  violation  of  this
Agreement  or  any  of  its  terms  will  constitute  immediate  and
irreparable injury to the Company and the Company shall have the
right  to  enforce  this  Agreement  and  any  of  its  provisions  by
injunction,  specific  performance  or  other  equitable  relief,  without
bond  and  without  prejudice  to  any  other  rights  and  remedies  that
the  Company  may  have  for  a  breach  or  threatened  breach  of  this
Agreement.

  I  agree  that  if  the  Company  is  successful  in
whole or in part in any legal or equitable action against me under
